Three wooden beams and two steel plates are securely bolted together to form the composite member shown. Using the data given in the table, determine the largest permissible bending moment when the member is bent about a vertical axis. Take x= 6 in. Modulus of elasticity Allowable stress Wood 2 x 106 psi 2000 psi 2 in. 2 in. 2 in. X Steel 29 X 10 psi 22,000 psi The largest permissible bending moment when the member is bent about a vertical axis is kip-in.
