Please help!! we need to find the displacement using matrix method. We need to find k, and do matrix for member 1 and member 2 and also global matrix.
Grading System: Write the given (2 pts), draw the equivalent FBD or diagram (6 pts), give the formula (2 pts), Solve the values of K (2 pts each) create matrix per member (5 pts. each), write the global matrix (10 pts.) and solve the unknowns and box your final answer (4 pts. each) Problem Statement: A L = 10 ft A. 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 in2 and E = 10 x 106 psi, compute the elongation of each rod and the horizontal and vertical displacements of point B. Assume a = 30° and = 30°. B a 0 L= 6 ft P С Figure P-216 and P-217
