displacement

Problem 217
Solve Prob. 216 if rod AB is of steel, with E = 29 × 10⁶ psi. Assume α = 45° and θ = 30°; all other data remain unchanged.
 

Problem 216
As shown in Fig. P-216, two aluminum rods AB and BC, hinged to rigid supports, are pinned together at B to carry a vertical load P = 6000 lb. If each rod has a cross-sectional area of 0.60 in.² and E = 10 × 10⁶ psi, compute the elongation of each rod and the horizontal and vertical displacements of point B. Assume α = 30° and θ = 30°.
