Question: 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

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 (2) is measured as -3,300 m/m. Use the dimensions L1 = 1,600 mm, L2 = 1,200 mm, a = 240 mm, b = 420 mm, and c = 180 mm. Determine: The contraction in bar (2) The elongation and the normal strain in bar (1) Displacement of point D
