A lap joint is to be made connecting a $-in.-thick strip of stainless steel to a :-in.-thick strip of alum inurn. The strips are 1 in. wide, and the epoxy used has a shear strength of 3000 psi; the aluminum has a tensile strength of 20,000 psi, and the stainless steel has a strength of 80,000 psi. If a safety factor of 3 is applied, over what area should the epoxy be applied?

a. Make a sketch of the joint.

b. Calculate the design load. (15,000 lb)

c. Calculate the shear area. (5 in.', or L = 5 in.)

d. What do you expect to fail? Explain your answer. (Aluminum)
