1. The overhang beam is subjected to the uniform distributed load having an intensity of w = 50 kN/m. Determine (a) the maximum shear stress developed in the beam; (b) the maximum bending stress developed in the beam. (a) Maximum shear stress occurs at the N.A. (a) Maximum bending stress occurs at the top fiber Or at the bottom fiber of the beam, i.e., y = ±0.05 m ππππππππ = − πππππππππ¦π¦ πΌπΌ = − ( 1 2 × 150ππππ × 3ππ)(±0.05ππ) 1 12 (0.05ππ)(0.1ππ)3 = ±2700 ππππππ (+ tension, - compression) 2 2. The beam is subjected to a shear of V = 2 kN. Determine the average shear stress developed in each nail if the nails are spaced 75 mm apart on each side of the beam. Each nail has a diameter of 4 mm.
