AME20213 – Spring 2011 – Lecture No. 5
Pre-Class Reading: 3.1-3.3
Subject: Measurement Systems and Sensors
Approach: We will conclude analyzing the Wheatstone bridge and its various uses. Then,
we will begin measurement systems. We will overview the main components of a
measurement system and then focus on sensors, the first component.
Take-Home Assignment (L5P1): Write an abstract of the simple cantilever-beam
experiment that we conducted in class, which involved the results that you plotted. Refer
to the description of an abstract that is provided on the class web site under Laboratory
Groups and Information. This abstract must be typed, professional looking, and be turned
in at the beginning of the next class (Thursday, March 3). It will be graded by a TA who
is not familiar with the experiment and then returned to you.
Take-Home Assignment (L5P2): As a test of your newly gained understanding of
analyzing electrical circuits, work Homework Problem No. 3 (Section 2.13). This also is
due at the beginning of the next class (Thursday, March 3) but should be done on
separate paper.
By Now You Should:
• Determine the equivalent resistance, capacitance and inductance of series and
parallel combinations of resistors, capacitors and inductors
• Know the definitions and units (where appropriate) of electrical charge,
anode, cathode, conventional; current, actual current, voltage, DC, and AC
• Know Kirchhoff's laws
• Apply Kirchhoff's laws to elementary DC and AC circuit analysis
• Know the relationship between input and output voltages and the resistances
of a Wheatstone bridge
• Know the relationship between resistances for a balanced Wheatstone bridge
