The crank below (Figure 1.1) A bicycle crank is fitted with a strain gauge and loaded as shown in Figure 1.2. The a 100 lb force is applied. The bicycle crank's material is aluminum 6061-t6, the Young's modulus is 10,000 ksi, and the Poisson's Ratio is .33. Using hand calculations and ANSYS Workbench, determine the strain measured by the strain gauge.

The dimensions of the bike crank are shown below.
