An extruded polymer beam is subjected to a bending moment M. The length of the beam is L = 660 mm. The cross-sectional dimensions of the beam are b1 = 31 mm, d1 = 117 mm, b2 = 19 mm, d2 = 19 mm, and a = 6 mm. For this material, the allowable tensile bending stress is 14 MPa, and the allowable compressive bending stress is 9 MPa. Determine the largest moment M that can be applied as shown to the beam.
