= 02 = 0, and the dimension L is constant. Assume the bars are made of the same material with elastic modulus E. (a) Analyze the model shown and calculate the forces and stresses in each bar (leave in terms of F, Aand A) (b) Calculate horizontal and vertical displacements of the load point, uz and uy respectively (use virtual work). They should be in terms of F, A, 0, L, and E.
