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 4750 µm/m. Assume initial rod lengths of L1 = 1,250 mm and L2 = 2,000 mm. Determine the normal strain in rod (2). (2) L2 (1) (1) B Rigid bar O 2771 µm/m 1846 um/m O 2437 um/m O 2172 um/m O 2969 µm/m
