A wood beam reinforced by an aluminum channel section is shown in the figure. 150 mm 232 mm 38 mm 6.5 mm 163 mm The beam has a cross section of dimensions 150 mm x 232 mm, and the channel has a uniform thickness of 6.5 mm. If the allowable stresses in the wood and aluminum are 8 MPa and 46 MPa, respectively, and if their moduli of elasticity are in the ratio 1 to 6, what is the maximum allowable bending moment for the beam? Enter the magnitude in kN- m. (Assume that the component parts of the beam are securely bonded by adhesives or connected by fasteners. Also, be sure to use the transformed-section method in the solution.) kN- m

The beam has a cross section of dimensions 150 mm x 232 mm, and the channel has a uniform thickness of 6.5 mm. If the allowable stresses in the wood and aluminum are 8 MPa and 46 MPa, respectively, and if their
moduli of elasticity are in the ratio 1 to 6, what is the maximum allowable bending moment for the beam? Enter the magnitude in kN • m. (Assume that the component parts of the beam are securely bonded by
adhesives or connected by fasteners. Also, be sure to use the transformed-section method in the solution.)
