Question
The cross-section of a wooden, built-up beam is shown below. The dimensions are L 180 mm and w = 20 mm. (Figure 1) Determine the magnitude of the moment M that must be applied to the beam to create a compressive stress of ap 40 MPa at point D. Also calculate the maximum stress developed in the beam. The moment Mis applied in the vertical plane about the geometric center of the beam. Express your answers, separated by a comma, to three significant figures. ▸ View Available Hint(s) M = max —| ΑΣΦ ↓ f t O ( kN-m, MPa
