Link AB, of width b = 2 in. and thickness t = 1414 in., is used to support the end of a horizontal beam. The average normal stress in the link is -18 ksi and the average shearing stress in each of the two pins is 12 ksi. Determine the average bearing stress (ksi). **The way I had solved it was that I used the given normal stress to first find the P force needed to plus into my bearing stress formula. I still however need the diameter. The answer key says to use the given shear stress equation to find the diamter, how do you know to use that and not the shear stress formula again?
