3. A wood beam (1) is reinforced on its lower surface by a steel plate (2) as shown in the figure below. Dimensions of the cross section are by = 230 mm, d = 400 mm, b² = 170 mm, and ( = 20 mm. The elastic moduli of the wood and steel 140 E₁ = 12.5 GPa and E₂ = 200 GPa, respectively. The allowable bending stresses of the wood and steel are 8 MPa and 140 MPa, respectively. This cross section is used for a simply supported beam that spans 9 m. What is the maximum moment that beam can support? Wood beam (1) Steel plate (2) b₂
