A rigid bar ABCD is supported by two bars as shown. There is no strain in the vertical bars before load P is applied. After load P is applied, the normal strain in bar (1) is -690 μm/m. Assume a = 280 mm, b = 420 mm, c = 160 mm, L₁ = 900 mm, and L2 = 1400 mm. Determine: (a) the normal strain in bar (2). (b) the normal strain in bar (2) if there is a 1-mm gap in the connection at pin C before the load is applied. (c) the normal strain in bar (2) if there is a 1-mm gap in the connection at pin B before the load is applied. a b B (1) Rigid bar L₁ C P L2 (a) Determine the deformation (positive if stretches, negative if shortens) of bar (1).
