Have one of two load cells. Took a little less than a week to receive this
one. As long as they are in stock at Futek and Maxwell Bennett
Associates isn’t backed up, we shouldn’t have a problem. Contingency
Plan: Find another company with load cells or borrow from Dr. Day.
There has been a lot of literature research done. Multiple papers have
shown different ways to quantify stress/strain. Must adapt their ideas to
the machine we create.
Due to the small displacements and loads created by this system, when
using the concept design, it is important that we keep strict
measurement on our angles when manufacturing the test stand.
Lead screws must be ordered. Depending on the company they are
purchased from (McMaster-Carr or other) they must arrive in an
applicable time frame.
As seen on the previous membrane indenter, the load cell wire can get
caught in the lead screws and be mangled. Avoiding this on this design
would be ideal.
Mounting the sample with sutures could provide human error as far as
10/1/08
the placement of multiple sutures on one side. Other option would be to
make a clamping system. The clamping system could over constrain the
membrane material.
Josh needs to be able to create a labview program that can run two
motors, collect data from two motor encoders and two load cells.
Rework on the program is expected, however, rework must be
minimized. Integration of camera element into the labview software
might facilitate outside assistance from J.D. Wellin.
The base is solely for combining all the electrical and other mechanical
aspects into one package. Lead time should be minimal and machining
should be done with quality in mind.
Cycle time must be minimal but not overly important.
Downtime/Rework must be minimal. Project group is already a bit

behind as far as the schedule. A broken machine would not be ideal nor
would rework. We cannot afford to reorder any electrical parts either.

Risks are often categorized on the basis of risk type or impact to the project, to help teams organize and insure completeness of the risk assessment. Risks
impact projects in 3 primary ways: performance (features, functionality, quality), schedule, or cost. Types of risk include: technical, quality, or performance
(eg. high-risk technologies or changes in standards, unrealistic features or performance goals); project management risks (eg. time and resource allocation,
poor planning); organizational risks (eg. inconsistent team priorities); external risks (eg. regulatory, customer priority changes, weather). Some risks fall into
multiple categories, so you may want to use a categorization scheme only as an aid to completing the assessment.

Choose a meaningful scale (eg. High, Med, Low; or 1=Critical, 2=High, 3=Med, 4=Low)
