a.The cross-section of a wooden, built-up beam is shown below. The dimensions are L=120mm and w=20mm.
(Figure 1). Determine the magnitude of the moment M that must be applied to the beam to create a compressive stress of ?D=20MPa at point D. Also calculate the maximum stress developed in the beam. The moment M is applied in the vertical plane about the geometric center of the beam.
