An extruded polymer beam is subjected to a bending moment M. The length of the beam is L-760 mm. The cross-sectional dimensions of the beam are b, = 33 mm, di = 102 mm, b2 = 20 mm, dz = 20 mm, and a= 6.5 mm. For this material, the allowable tensile bending stress is 10 MPa, and the allowable compressive bending stress is 13 MPa. Determine the largest moment M that can be applied as shown to the beam.
