An extruded polymer beam is subjected to a bending moment M. The length of the beam is L = 680 mm. The cross-sectional dimensions of the beam are b₁ = 39 mm, d₁ = 88 mm, b₂ = 23 mm, d₂ = 23 mm, and a = 8 mm. For this material, the allowable tensile bending stress is 12 MPa, and the allowable compressive bending stress is 10 MPa. Determine the largest moment M that can be applied as shown to the beam. b₂ a M y| d₁ B L Answer: M i MI N•m d₂ b₁
