A copper rod of diameter 1 cm and length...

A copper rod of diameter 1 cm and length 8 cm is drawn in to a wire of length 18 m of uniform thickness. Find the thickness of wire.

A

the same stress and strain

B

the same stress but different strains

C

the same strain but different stresses

D

different stresses and strains.

Text Solution

Verified by Experts

The correct Answer is:
B
Same force is applied to each wire having equal area of cross-section, so stress is same but extensions will be different for wires of different materials. So equal stress but different strains are there in the two wires.
