A rigid horizontal bar ABC is supported by three vertical rods. There is no strain in the rods before load P is applied. After loap P is applied, the axial strain in rod (1) is

Determine the deflection of the rigid bar at B and the normal strain in rods (2) if there is a 0.60-mm clearance in the connection between rod (1) and the rigid bar before the load is applied.
