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 μm/m. Use the dimensions L1 = 1,600 mm, L2 = 1,200 mm, a = 240 mm, b = 420 mm, and c = 180 mm. Determine (a) the normal strain in bar (1). (b) the normal strain in bar (1) if there is a 1 mm gap in the connection at pin C before the load is applied. (c) the normal strain in bar (1) if there is a 1 mm gap in the connection at pin B before the load is applied.

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 P is applied, the normal strain in bar
(2) is measured as −3,300 μm/m. Use the dimensions L1
= 1,600 mm, L2 = 1,200 mm, a = 240 mm, b = 420 mm,
and c = 180 mm. Determine
(a) the normal strain in bar (1).
(b) the normal strain in bar (1) if there is a 1 mm
gap in the connection at pin C before the load is applied.
(c) the normal strain in bar (1) if there is a 1 mm
gap in the connection at pin B before the load is applied.
