Fig P9 shows a drawbridge being rasied by a cable EI. The structure is a loaded truss consisting of a pinned assembly of members(links) joined at their ends designed to from a rigid structure. The four joint loadings shown result from the weight of the roadway.
Calculate the forces in each link by the method of joints. In each case, state whether it is in tension or compression.
