Question

Structural Analysis

Consider again the two-bar truss in the figure below, again subject to the concentrated load F. However,for this problem, the bars are not necessarily the same size A, + A2 and 0, # 02. The dimension L is stillconstant.

(a) Analyze the model and calculate the bar forces and stresses in terms of F, A1, A2, 0,, and 02.

(b) Calculate horizontal and vertical displacements of the load point, uz and uy respectively (use virtual work). They should be in terms of F, A1, A2, 01, 02, L, and E.
