A rigid bar ABCD is supported by two bars as shown in Figure below.
A rigid bar ABCD is supported by two bars as shown in Figure below. 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 - 570 μm/m. 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.
