4-62. If the 50 mm diameter supporting rods are made from steel, determine the average normal stress developed in each rod when P = 450 kN. 4-63.If the supporting rods

of equal diameter are made from A992 steel, determine the required diameter to the nearest 3.175 mm of each rod when P = 450 kN. The allowable normal stress of the steel is o allow = 170 MPa.
