Three steel plates, each 16 mm thick and width of 300 mm are joined by two 20 mm rivets as shown. Assume the rivet hole diameter = 23 mm.

A. If the load P= 50 KN, determine the tensile stress of the plates.

B. If the load P= 50 KN, determine the largest bearing stress acting on the rivets.

C. If the ultimate shear stress for the rivets is 180 MPa, what ultimate force Pu is required to cause the rivets to fail in shear? Neglect friction between the plates.
