A rigid steel bar is supported by three rods as shown. There is no strain in the rods before the load P is applied. After load P is applied, the normal strain in rods (1) is 2160 µm/m. Assume initial rod lengths of L₁ = 1,250 mm and L2 = 2,000 mm. Determine the normal strain in rod (2) if there is a 2-mm gap in the connection between the rigid bar and rod (2) at joint B before the load is applied. (1) A 4₁ (2) Rigid bar O 481 μm/m O 317 μm/m O 249 μm/m O 408 μm/m O 350 μm/m B P L₂ C (1)
