Question 3 [10 marks] A rectangular beam 100 mm deep and 150 mm wide is simply supported over a span of 4 m. What uniformly distributed load per metre may the beam carry, if the bending stress is not to exceed 100 N/mm2? Question 4 [ 25 marks] The simply supported beam shown in Figure 2 is subjected to concentrated loads. Solve for the following. 1.1 Calculate the reaction at A and D. [6] 1.2 Calculate the values of shear force and bending moment at each point. [9] 1.3 Draw shearing force diagram and bending moment diagram. [5] 1.4 Determine the maximum shearing force and the point at which it occurs. [2] 1.5 Determine the maximum bending moment and the point at which it occurs. [2] 1.6 Determine the position of contraflexure. [1] 90kn 170kn | A D B C 6m 6m 6m Figure 2
