A joint has the same geometry as Ex. 84, but the lower member is steel. Use Eq.

Question:

A joint has the same geometry as Ex. 8–4, but the lower member is steel. Use Eq. (8–23) to find the spring rate of the members in the grip. Hint: Equation (8–23) applies to the stiffness of two sections of a joint of one material. If each section has the same thickness, then what is the stiffness of one of the sections?
