The plane frame of Prob. 13.12 is subjected, in addition to the downward forces Q at B and C, to two horizontal forces at the same nodes, each equal to Q/10 pointing to the right-hand side. Find the nodal displacements and the member end-forces. Take l = 6c;

Prob. 13.12

Find the displacement D due to an axial force F applied at the end of a straight prismatic bar of length l, assuming the stress–strain relation σ = C( − 2/4), where C = constant. Take F =0.7Ca, with a being the cross-sectional area. Apply Newton-Raphson’s technique and give the answers for two iterations.
