Transcribed Image Text:4. A rigid steel bar is supported by three circular rods as shown in Figure below. There is no
strain in the rods before the load P is applied. After load P is applied,
in rod (2) is 1,090 µ. Assume initial rod lengths of L1 = 3400mm. and L2 = 1800mm.
Assuming the system is symmetrical, determine:
a. The normal strain in rods (1).
b. The normal strain in rods (1) if there is a 2mm gap in the connections between
normal strain
the rigid bar and rods (1) at joints A and C before the load is applied.
c. The normal strain in rods (1) if there is a 2mm gap in the connection between
the rigid bar and rod (2) at joint B before the load is applied.
