Problem 2.

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.
