Two wires ( A ) and ( B ) are stretched by the same load. If the area of cross section of wire'A' is double that of 'B', then the stress on 'B' is
Options
- AEqual to that on ( A )
- BTwice that on A
- CHalf that on A
- DFour times that on A
Correct answer
B. Twice that on A
Step-by-step solution
Stress (= F A ). If A is doubled stress will be halved.
