Link AB, of width b = 2 in. and thickness t = 1/4 in., is used to support the end of a horizontal beam. Knowing that the average normal stress in the link is -20 ksi, and that the average shearing stress in each of the two pins iS 12 ksi, determine (a) the diameter d of the pins, (b) the average bearing stress in the link.
