1 LABORATORY EXERCISES
2.1 Description of Labs
There will be four labs and one computer simulation in the fall semester. These labs will be
performed independent from class time. You will work in groups of your choice that are not larger
than four members. The data collection aspect of these labs must be performed during the 2-hour lab
period offered Monday to Thursday after school. Analyses can effected in any location of
convenience to you and your lab group. Below will be deadlines for the submission of the formal
report for each lab experience. Remember you are required to submit TWO copies of your
papers. One will be returned and the other kept on file. In addition, you must supply a single sheet of
paper detailing the efforts of each person in the group and it must include the signatures of all
members.
Due to bandwidth restrictions and formatting dramas, no electronic submissions will be
accepted. I realize .pdf format resists this, but I think proper that you effect the printing for
these reports instead of me.
Late submissions are NOT acceptable without proof of insurmountable difficulties for all 4
members of the group. Prevent this by having the report stored on more than one computer or on a
web page and prepared a few days in advance.
The details will of the experiments and the project will be made clear when this document is
released to the class on the first day of school. Full use of your graphing calculator, Maple, Excel and
possibly some programming will be necessary to complete some of the analysis required for these
labs. Here is your chance to be a scientist!
You are expected to design the procedures and analysis for each experiment. You will be marked
on how well you first conform to the requirements of form and the basic academic constraints of the
experiment and then on how you handle the more subtle and technical aspects. This is a measure of
your scientific acumen and creativity. Yes, you can do more, but does it really contribute to the
experiment? You need to weigh all of this very carefully. You will not have time to waste in your
laboratory experience in university (or professional life) so find ways to check that you are on the
right track before you waste a lot of time.
2.4 Marking Rubric
On the next page is a copy of the rubric that will be used to grade your formal lab reports.
Comments from Mr. van Bemmel will be copiously written on the report and a short discussion will
be had with each group when the report is returned. This may have to happen outside of class
depending on our schedule. Students who wish further input should make an appointment with Mr.
van Bemmel at a time of mutual convenience.
Although Mr. van Bemmel will guide you and answer specific questions related to form and
other aspects of a paper, he will not “go over the report” prior to handing it in. You get one chance
for your mark. You are expected to read EVERY WORD of the lab manual and the course profile
that pertain to submission format and use it properly.
2.4.1 Lab Notebooks
You must submit your lab notebook along with your formal report. One Notebook per
report please.

SUBMISSION TYPE
GROUP SIZE
You must use two cans of soup. One is a consommé and the other is a
cream soup. The cans must have the same-labelled mass and have the same
dimensions at least to eye. It is better if the soups chosen do not have chunks
of material in them.
These cans are to be rolled down two ramps and then on to a flat surface.
The slope must be otherwise smooth and so must be the floor. One slope is to
be slight permitting the consommé can to roll further. The other must be
much steeper and result in the cream soup rolling further. You may have to
cover the slopes with some material to prevent the can from slipping. You
may also modify the floor ramp interface to allow the can to smoothly
transfer from the ramp to the floor without appreciable bouncing. (If you
think this matters)
In either case, one soup can will roll further than the other. Why? I want a
complete analysis of the energy that is imparted to these cans and where it
goes. What is going on inside the cans? What is the reason for the variation or
lack thereof in the results from the two ramps? Justify your theory with some
intelligent analyses. Full uncertainty analysis is expected. Innovative
techniques to obtain better results are of interest.
Your report will follow all the constraints given in the course package.
However, it will also conform to the page limit set forth below. Using
appropriate and reasoned analysis your report must answer the question as
why one can rolled further (in both experiments) and discuss using
mathematical models the probable situation inside the cans during both
experiments as can be inferenced by motion of same.
4 pages + 1 page indicating the duties performed by each member. Please
print them on BOTH sides of the paper.
Only equipment found in the school lab or reasonable contents of a
student’s pencil case are permitted. Experiment data must be collected at the
school using the aforementioned equipment unless express permission to the
contrary has been secured. Analyses can be performed in any location.
Not later than 1200 – 02 October 2009 – Friday – No Extensions
Paper ONLY. Double-sided. TWO identical copies must be submitted by

EXPERIMENT 1A – MECHANICS
COLLISION SIMULATION
BASIC
REQUIREMENTS
You will write a simulation using code in C, C# or C++ that will simulate a two dimensional collision.
This code will first verify itself solving a 2D collision that is first head on with a motionless target, then a
glancing collision with a motionless target. The verification is taken from a photocopy of a worked problem
or an example from a text book that will show conclusively that your program is producing comparable
results
The program will then analyze the situation where the target is moving.
This is a challenging problem algebraically, but it can be done using a simulation. It is a problem that you
can intrinsically understand and thus find the benefit of producing a simulation for these types of problems.
The real problem you will face here is how to model the actual events around the collision itself. We know
that the materials compress for very short time span and spring back. Assume for this experiment that your
collisions are elastic.
Since our laboratory equipment is limited in this area, you will use a stress ball, map out its compressive
properties, and use these in your simulation.
BONUS: You may choose to include the rotation of the objects either as an initial condition and/or because
of their impact for a maximum 20% bonus, but it must be done properly and with sound reasoning and most
importantly as a simulation not a rendering. For clarity consider my primer on Simulations which can be
found on my web page www.hmvb.org
Submission format: Your submission must include.

3. Photocopies of the sample problems you have used to verify the operation and accuracy of your
program.
4. Photocopy of a 2D glancing collision with a moving target
5. No marks or consideration given for any GUI work regardless of the quality
6. A block diagram (Flow chart) of what your program is doing to produce the data.
7. Analysis of the stress ball spring constant experiment including any uncertainties. Is it linear etc? Is k a
value or function?
Not enforced
Only equipment found in the school lab or reasonable contents of a student’s pencil case are permitted.
Experiment data must be collected at the school using the aforementioned equipment unless express
permission to the contrary has been secured. Analyses can be performed in any location.
Translation. The analysis of the stress ball must be done at school in our lab. The rest can be done at your
convenience, but the program must be transportable to school and runable there.

You are to investigate the effects that bob mass and the length of a
pendulum have on its period. This is to be done at various release angles and
the effect the release angle has on the pendulum’s period must be modelled.
The differential equation for the motion of the pendulum must be derived
and the constants measured. For small values of theta, the DE can be
simplified using the small angle equation. You must, however, be prepared to
defend what range you consider a small angle and how this estimation affects
the overall precision of your work. You are also expected to empirically
model the effects of large values of theta on the period. Thus your final
expression will be something like Period(theta, Length) = Ideal
Period(length) + Period Perturbation (theta, length). CAUTION: Observe that
the square root of small g is essentially equal to Pi. Do not ignore this!
You are also expected to let your pendulum swing for an extended period
to determine the damping coefficient involved. You should predict what
value for this coefficient is expected due in part to air resistance and compare
it to what is measured.
4 pages + 1 page explaining the duties of each team member. Please print
them on BOTH sides of the paper.
Pendulum should be set in a V to ensure motion in only two dimensions.
Any equipment in the school inventory not in current use by a teacher or the
typical items found in a student’s pencil case. Data collection must occur
within the school proper using the aforementioned equipment unless special
permission has been granted by the instructor.

EXPERIMENT 3 – ELECTRICITY
DC CIRCUIT ANALYSIS
AC INTRODUCTION
You will construct two separate circuits and analyze each of them as
required below.
BASIC
REQUIREMENT
ESSENTIAL
REPORT
INFORMATION
PAGE LIMIT
EQUIPMENT
RESTRICTIONS
Circuit 1: Resistor network – Connect a bridge resistor network and
then predict using KCL and KVL the voltages and currents of each segment.
Then measure the same and verify these values. Account for any
discrepancies. Full use of uncertainty analysis is required. Caution: It helps to
choose resistors that have prime numbers or your linear system can be more
easily dependant making the theoretical solution harder to find. Also, do not
select resistors for the different branches of your circuit that differ by more
than 1 order of magnitude as this will make your uncertainty analysis
difficult.
Circuit 2: RC Circuit. You will construct a RC circuit and then observe
the charging and discharging curves. You will have to choose values for R
and C that can be read with the typical operational window of the I-books.
These can be determined by appropriate attention to the theory of this type of
electrical circuit.
HINT: In addition, the capacitor when nearing full charge will behave
like a very large resistance. These phenomena will cause your voltmeter to
give erroneous reading when in parallel to the capacitor. Part of your
methodology will be to devise a work around to this issue and explain it in
your paper
Circuit 3: Oscilloscope Familiarization You will connect the
oscilloscope to the AC signal generator and obtain a waveform. From this
you will measure the wave characteristics on the screen of the scope. The
frequency counter can then be used to verify the frequency. You are expected
to image the waveform from the screen of the scope. The TI-8x’s, I-books are
not permitted on this segment as you are expected to learn the use and
operation of an oscilloscope. You must use the analog scopes for this
exercise. The digital scope is NOT to be used for this segment unless express
permission from your instructor is given.
Your report will follow all the constraints given in the course package.
However, it will conform to the page limit set forth below. The resistance of
the CBL will begin to affect the readings you get from the voltage probe. You
will have to sort this out.
You are expected to discuss the symmetry or lack thereof of the RC
profiles.
Your report must indicate if your research confirms or challenges the
accepted situation.
4 pages + 1 page indicating the duties performed by each member. Please
print your work on BOTH sides of the paper.
You may use digital and / or analog voltmeters. You may also use I-books
/ TI8x / CBL voltmeters if you wish and the equipment is available. You must
use Kirchoff’s work to solve these circuits. Thevenin and Norton

how these theorems conform to the work you have done, but your analysis
cannot be justified exclusively by Norton or Thevenin Theorems.

Not more than 4 people. No gender ratio restrictions. Groups may be

Note: There is only ONE unique solution to the KVL circuit in part 1. You have to be sure that the
equations you choose are not linearly dependant. This can be checked when you set up your matrix by taking
the determinant.

EXPERIMENT 4 – ELECTROMAGNETISM
AC CIRCUIT ANALYSIS
Circuit 1: RC Phase shifting You will reconstruct the series RC circuit that
was used during experiment #3. Measure whatever parameters you deem necessary
with whatever equipment the school can provide to measure the reactance of the
capacitor and the phase shift it generates between the current and the voltage
waveforms. Research the topic of Lissajous figures and measure them for this
circuit. Does the data from this observation compare well with other data collected
above. What is the common use of this technique? Choose your R and C values
carefully to encourage a sensible phase shift of current and voltage (You are
permitted to alter the parameters of both R, C and f to obtain a reasonable Lissajous
Figure. However, you are still expected to show what the phase shift would have
been with the components from your Lab 3 experiment. If the phase shift of these is
acceptable then fine otherwise predict and show that it is small and then choose new
components to complete this part of the experiment). Your theoretical knowledge
should guide you here. The values of these components have to be carefully
chosen to permit impedance matching. You should research this before
entering the lab. The results of this computation should also be included in your
analysis.
BASIC REQUIREMENTS
Circuit 2: CLR Circuit. Now connect a CLR circuit with components whose
impedance with match the output of the function generator and predict the natural
frequency of this circuit. (Show the reasoning here in your report please.) Make a
plot of frequency amplitude v. frequency and see if your resonance point is in fact
the natural frequency. Some analysis of your curve should be effected to obtain the
mathematically sound maxima here.
Circuit 3: Transformer Using the coils and magnetic cores provided by
school make a rudimentary transformer. Starting with a low frequency of 20
increase the frequency of the input voltage until the output voltage drops
considerably. It should be much higher. Why does this happen? Where does all
energy go?

Circuit 4: Solenoid Using the hall effect probe and DC power source of a low
enough voltage to keep the current in the coil at a safe level (ie. 1.5 V) measure the
B field inside the solenoid and also along it longitudinal axis. Compare the values
you obtained with those predicted by the theory describing your circuit. Consider
using the Helmholtz coils for this
Extension: Energize a second solenoid whose B field is similar, but not
necessarily exactly the same as the first one. Place the second solenoid proximate to
the first one at an arbitrary angle well of the axis. Compute the theoretical B field in
R3 as it is distorted by the two solenoids. NOTE: Proper solutions to this
challenging aspect can earn up to 110% on this paper. However, papers that do
not meaningfully undertake this aspect will not receive a grade in excess of
90%.

Your report will follow all the constraints given in the course package.
However, it will conform to the page limit set forth below. The resistance of the

to sort this out.
The directional ability of the Hall effect probe is a problem. This is exacerbated
by the local magnetic fields in the room. Part of the challenge is to sort out this
problem. To complete the extension described above you would have to carefully
locate the probe’s tip around the solenoid in 3D. This apparatus would be your own
design. (Course work primarily deals with the fields along the longitudinal axis of
the solenoid)
Your report must indicate if your research confirms or challenges the accepted

If not attempting the bonus then the page limit is the usual 4 pages.
Oscilloscopes must be used for the AC section of this work. The remainder can
be effected using any equipment in the school. The positioning tool that might be
used for the extension cannot be professional in origin or expensive and thus readily
obtainable or constructed by the team members from everyday materials.

REQUIREMENTS
PARTICULARS
You are required to construct a device that conforms to the following.
Using mechanical and electronic means, subject to the restrictions in this
assignment construct a device that can obtain the value of the local magnetic field in 3
dimensions. The project will be marked for its ability to accomplish this task and the
accuracy obtained. The display should be a digital readout and not a simple
mechanical gauge. This display should have three significant digits. A selector can be
used to obtain the readings for each cardinal direction, permitting the construction of a
single LED type display. The cycling of the display through the 3 axes can also be
automated electrically if you prefer.
The unit would be required to produce an accurate result within 5 seconds of a
change of the B field.
Originality is stressed in the design of this project. If your work is found to
conform in a major way to an existing design you marks for this aspect will not be as
impressive.
Engineers design things and technicians build them. Therefore, it will be your
burden to design your project prior to constructing it. Your group will be held
accountable for not only the quality and originality of your design, but also for how
well it conforms to your final project. Your outline will contain the following

check this. I expect some creativity and originality here not a simple copy
of an Internet project.
A wiring diagram of the device using established techniques and symbols
An overall set of procedures to construct and test this device. Tolerances
and expected performances during construction should be included.
A production schedule and a system to monitor same that can be produced
upon demand.
A budget whose total cannot exceed $150 CDN (Fair market value charged
for any gifts of material).
A pamphlet created in a quasi-professional manner that would accompany
this project that would be used for marketing purposes. Do be careful about
the claims you make, you will be held accountable!

EQUIPMENT
RESTRICTIONS
You may use basic stock materials, such as dowel or metal rods etc. for the
mechanical aspects, however the expectation is that you fabricate the device as
much as possible.
The electronic aspect restricts you only in the prohibition of interfacing with a
computer, using microcontrollers and other small computers. Your display device
MUST be of your own design/construction. Hooking it up to a simple voltmeter
would be an unsatisfactory choice. This would also apply to buying some type of
device box that connects to a computer. You are expected to do this the hard way.
You are NOT permitted to use weight sensing devices such as load cells or
piezoelectric devices. Nor are strain gauges permitted.
You may NOT construct your own power supply for this unit. Any aspects
of this project that use voltages greater than 12V must be CSA approved.
You have a budget of $150.00 CDN total for this project This includes any
“donations”. The limit is “fair market value” for the items you use in your project
You are strongly discouraged from attempting to use the school shops to
build this device.
They are understaffed and your safety is an insurmountable issue. The
construction of this device will largely have to occur outside of the building. If you
have intractable problems with this aspect come and see me.

DESCRIPTION
If the device works DURING the demo you will get full marks here. If you
can document (i.e. video or some other evidence) that it did work, but
something bad happened on demonstration day then you will earn at least 8
marks. Beyond that, it will be the teacher’s judgement as to how close you were
to getting it operational. By working the device should at least give readings that
are in the same direction as the (in)decrease of the load and proportional to the
stimulus
If you have begun your data display system, but it is not operational, you
cannot earn more than 3 marks here. If you have not begun constructing this and
have only the design then you will receive zero for this section.
For the rest of the marks you system would have to have some form of
calibration in that when it displays some level this has physical meaning and
that you have modelled and can be used to infer the mass. Hex/Octal readouts
are allowed, but will not receive the highest marks.
Specifically how well did the finished device correspond to that specified in
the prospectus? This goes right down to dimensions and electronic part
specifications etc.
1. All form rules enforced here (Operating Manual format)
2. Is the production schedule reasonable?
3. Did this group produce an up to date production status when asked?
1. How professional is the Operating Manual?
2. How professional is the Marketing Pamphlet?
