Determine the shear center and maximum contact pressure between the follower and cam

The problem is from advanced strength and applied stress analysis book. Determine the shear center for problem 5.22 and determine the maximum contact pressure between the follower and cam, the principle triaxial stresses, the maximum von mises stress and the approximate elastic deflection between the roller and follower for problem 5.80. Attached are the pictures of the problem and the figure. The expectation is to complete the questions with work shown.
