Part $2$: Truss analysis

The complex steel truss in Figure $1$ forms a part of a crane structure. The truss is pin supported at A and roller supported at C $.$ All truss members are pin jointed. A horizontal load of P is applied at joint E $.$ The Young's modulus of steel should be taken as $200$ GPa $.$ The load, geometry and cross$-$sections of the truss will be instructed to each student in class.
