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 isapplied, the normal strain in bar (1) is -950 μm/m. Determine:
(1)Determine the normal strain in bar (2) (positive if tensile, negative if compressive).
(2)Determine the deformation of bar (1) (positive if stretches, negative if shortens) if there is a 1-mm gap in the connection at pin C before theload is applied
(3)Determine the rigid bar deflection (positive if the bar stretches, negative if it shortens) of pin B if there is a 1-mm gap in the connection atpin C before the load is applied.
(4)Determine the rigid bar deflection (positive if the bar stretches, negative if it shortens) of pin C if there is a 1-mm gap in the connection atpin C before the load is applied.
