The bicycle crank is loaded such that the fitting on the right is fixed while the fitting on the left is loaded with a 100 lb force.

Using hand calculations and ANSYS Workbench, determine the strain measured by a 5.64 mm strain gauge centered at (3.3748, -0.09409, .375) away from the force and aligned in the y-direction.
