The simply supported beam in Fig QB1a is made by gluing two pieces of wood of rectangular cross-section as shown in Fig QB1b, i.e. the top board (flange) is glued onto the bottom board of the web. The supports at A and B exert only vertical reactions. 150mm T y 30mm A 4m C 30mm 150mm 6.5 kN/m Fig QB1a 4m B y = 0.120m Fig QB1b Calculate the support reaction forces, and hence sketch shear and bending moment diagrams indicating the values at A, B, C. Describe how shear force and bending moment vary along the beam; Compute the moment of inertia of the section about the neutral axis. The position of the neutral axis is y = 0.120m as shown in Figure QB1b; Determine the maximum shear stress in the glue necessary to hold the hoam together along the seam where they are joined

In structural engineering, a beam is a component made of a variety of materials (including steel alloys, and wood) that can resist loads applied laterally to the beam axis. Members, elements, rafters, shafts, and purlins are all terms used to describe be…
