A copper and a steel wire of the same diameter are connectedend toend. A deforming force F is applied to this composite wire which causes a total elongation of 1 cm. The two wires will have

A

same stress and same strain

B

same stress and different strains

C

different stresses and same strain

D

different stresses and different strains

Text Solution

Verified by Experts

The correct Answer is:
B
Tension is any of the wire is same at all points as cross sectional area are the same and tension also. So stress `(=F//A)` in both the wires would be the same but from Strain `= "Stress"/"Strain"` as `Y` is different for both, so train is different in both.
