I Prob. 2.7-8. An angle bracket ABC is restrained by a high- strength steel wire CD, and it supports a load P at A, as shown in Fig. P2.7-8. The diameter of the wire CD is d = in., and the diameter of the pin at B is dp = in. Determine the tensile stress in wire CD and the average direct shear stress in the pin at B. 15 -5 in.- P = 200 lb. a B P2.7-8 dw 4 in. View a-a of B
