An engineer wants to join two members perpendicularly, with materials they already have on hand. They have a link (shown here) that is 5 inches wide, called b, with an unknown thickness, called t. Based on the application, they know that the average normal stress in the link will be = -35 ksi. Likewise, the average shearing stress in the pins will be T = -20 ksi. This link will support a load of P = -87.5 kip. d d +5 b t (a) Determine thickness, t. (b) Determine the diameter, d, of each pin. The pins are equal diameter. (c) Determine the average bearing stress in the link.
