A Copper wire and steel of the same diameter and length are connected end to end and a force is applied, which stretches their combined length by 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.
