An extruded polymer beam is subjected to a bending moment M. The length of the beam is L= 740 mm. The cross-sectional dimensions of the beam are b1 = 35 mm, d - 101 mm, b2 = 21 mm, d2 21 mm, and a=7 mm. For this material, the allowable tensile bending stress is 13 MPa, and the allowable compressive bending stress is 13 MPa. Determine the largest moment M that can be applied as shown to the beam.
