In Figure Q3, the plane truss ABCDEHGFA forms part of the supports of a crane on an offshore oil platform. The crane exerts two forces, each of magnitude 122.5-kN, and acting vertically downwards on truss joints B and D. Determine the magnitudes of the axial forces in members AB, BC, EH and GH of the truss, and state whether they are in equilibrium or not
