Problem Specification

The crank below (Figure 1.1) 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. The dimensions (in inches) of the bike crank are shown below.
