6. The round bar shown has steel, brass, and aluminum sections. Axial loads are applied at cross sections A, B, C, and D. If the allowable axial stresses are 125 MPa in the steel, 70 MPa in the brass, and 85 MPa in the aluminum, determine the diameters required for each of the sections. Assume that the allowable stresses are the same for tension (T) and compression (C). 270 kN. Steel 245 KN 0.5 m B Brass 200 kN 0.5 m C Aluminum 0.5 m 225 kN
