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. An engineer wants to join two members perpendicularly, with materials they already have on hand.
