An Idealized support condition for a proposed bridge deck with a span of 10 m is shown in Figure Q3(b). The bridge was designed to carry a maximum moving load from a truck with three axle loads of 10 kN, 20 kN and 30 kN. Using the influence line method, evaluate the position of the truck that will give the maximum magnitude of the vertical reaction at A. Hence, determine the shear force and the bending moment at 3 m from support A. Consider that the truck could travel in either direction. (CO2-PO2)(C5) (10 marks) 30 KN 20 KN 10 KN X 3 m 1.5 m B 10 m
