Shear: 9a The two 0,75x4.0-inch tension bars shown below are riveted together through two 0.8x 6.0-inch splice plates, and rivets of 1.0-inch diameter. The allowable stress for the bars and

splice plates is o = 20.0 ksi, the allowable shear stress on the rivets is t = 9.0 ksi , and the allowable bearing stress on the rivets and splice plates is o = 25.0 ksi . Find the maximum bearing load P such that none of the allowable stresses will be exceeded. Which part of this connection would you first replace to make it more efficient?
