A wooden beam is fabricated from boards as shown, which are fastened together with screws and glue, as shown in the figure below. The screws are uniformly spaced along the span of the beam at intervals of 150 mm. The beam will be positioned so that bending occurs about the horizontal axis. The maximum shear force in the beam is Vy-120 KN. Determine: (a) Determine the shear stress at the glue. (b) Determine the shear force in each screw. (c) Draw (without values) the distribution of the shear stress along the depth of the cross-section 20 0 m m 25 mm 200 mm 25 mm 10 0 m m 25 mm
