A rigid bar ABCD is pinned at A and supported by two steel rods connected at B and C, as shown. There is no strain in the vertical rods before load P is applied. After load P is applied, the normal strain in rod (2) is 800 με. Determine : (ajthe axial normal strain in rod (1). b)the axial normal strain in rod (1) if there is a 1 mm gap in the connection between the rigid bar and rod (2) before the load is applied. 2.7 m 1.5 m Rigid bar 2.5 m
