Q3. Explain what is meant by “maximum absolute moment and shear in beams”. Your explanation must be based on cantilever beams and simply-supported beams subjected to single and multiple concentrated loads. (15 marks) Given a 3-axle truck with the following loads as shown in Figure Q3, determine the position of the truck that produces the maximum moment on a 24 m simply supported bridge when the train moves on the bridge. You may ignore the weight of the bridge and...
