Continue to analyze the bicycle brake lever started in the lecture. We want to conduct some
classical calculations and compare the solution to the SolidWorks simulation results. After
defeaturing the model, the brake lever handle is a 3/8-in x 3/8-in square cross section.
To do this conduct the following:
a)
Use the Probe feature to create a graph of bending stress from top to bottom of the brake
lever at a location two corner nodes to the right of the fillet tangency line shown bold in
figure below
b)
Manually calculate the bending stress at the top surface of the lever surface and compute
the percent difference between classical and finite element solutions. Clearly label
locations of all calculations.
c)
Use the Probe feature to create a graph of shear stress due to bending across the front face
of the brake lever at the same location used in the part (a).
d)
Manually calculate the maximum shear stress due to bending using classical stress
equations, then determine the percent difference between classical and finite element
solutions. Clearly label locations of all calculations.
Include a page with the analytic solution, a page or two with the finite element results
(please use white backgrounds for images), and a page with the percent differences clearly
labeled with a box around the answers.
