The lap joint is connected by four rivets. Assuming that the axial load P = 30000 lb is distributed equally among the rivets, find the diameter of each rivet if the allowable working stresses are 16 ksi, 22 ksi and 12 ksi for shear stress of the rivets, bearing stress between the rivet and plate and tensile stress of the plate respectively. P 1-13 8 IN.

The assembly consists of three disks A, B and C that are used to support the load of 140 kN. Determine the smallest diameter d, of the top disk, the diameter d₂ within the support space, and the diameter d of the hole in the bottom disk. The allowable bearing stress for the material is (allow)b = 350 MPa and allowable shear stress is allow=125 MPa. B A 140 KN - dz d₂ 20 mm 10 mm

02: The rigid platform has negligible mass and rests on two steel bars, each 250.00 mm long. The center bar is aluminum and 249.90 mm long. Compute the stress in the aluminum bar after the center load P= 400 kN has been applied. For each steel bar, the area is 1200 mm2 and E= 200 GPa. For the aluminum bar, the area is 2400 mm2 and E 70 GPa Rigid platform Steel Ahmum Steel
