Question
An extruded polymer beam is subjected to a bending moment M. The length of the beam is L = 900 mm. The cross-sectional dimensions of the beam are b1 = 37 mm, d1 = 88 mm, b2 = 22 mm, d2 = 22 mm, and a = 7.5 mm. For this material, the allowable tensile bending stress is 18 MPa, and the allowable compressive bending stress is 14 MPa. Determine the largest moment M that can be applied as shown to the beam.
