Do not round intermediate answers. Give your final answer(s) to three decimal places. Check your units. A bar having the cross section shown has been formed by securely bonding brass and aluminum stock. Using the data given below, determine the largest permissible bending moment when the composite bar is bent about a horizontal axis. Modulus of elasticity Aluminum 80 GPa Brass 105 GPa Allowable stress 100 MPa 160 MPa M = kN-m Aluminum 16 mm 16 mm 16 mm Brass 36 mm 36 mm 16 mm
