Problem 7 

In the hanger shown, the upper portion of link ABC is 3/8 in. thick and the lower portions are each 1/4 in. thick. Epoxy resin is used to bond the upper and lower portions together at B. The pin at A has a 3/8 in. diameter, while a 1/4 in. diameter pin is used at C. Determine (a) the shearing stress in pin A, (b) the shearing stress in pin C, (c) the largest normal stress in link ABC, (d) the average shearing stress on the bonded surfaces at B, and (e) the bearing stress in the link at C.
