Question

Two flat bars loaded in tension by forces P are spliced using two rectangular splice plates and two 5/8-in. diameter rivets (see figure). The bars have width b = 1.0 in. (except at the splice, where the bars are wider) and thickness t = 0.4 in. The bars are made of steel having an ultimate stress in tension equal to 60 ksi. The ultimate stresses in shear and bearing for the rivet steel are 25 ksi and 80 ksi, respectively.

Determine the allowable load Pallow if a safety factor of 2.5 is desired with respect to the ultimate load that can be carried. (Consider tension in the bars, shear in the rivets, and bearing between the rivets and the bars. Disregard friction between the plates.)
