Question: rods i and 2 are initially stressfree and attached vertically...

Question details

Rods (I) and (2) are initially stress-free and attached vertically to the rigid bracket BCD at points B and D. Each of the two rods has a cross-section area of A, a Youngs modulus of E, and a length of L. BC has a length of 2a, whereas CD has a length of a. An external load P is applied vertically to BCD at B. Assume that the planar rotation of rigid bracket BCD is small a) Determine the elongation of rods (1) and (2). b) Determine the axial stresses induced in rods (1) and (2). Express your results in terms of the parameters you need.
