Two wires of the same radius & material having length in the ratio of 1 : 2 are stretched by the same force. The strain produced in the two wires will be in the ratio of__________________?
Correct answer: A. 1 : 1
- A. 1 : 1
- B. 1 : 2
- C. 2 : 1
- D. 1 : 4
Explanation
Strain equals stress divided by Young's modulus, and both wires have the same cross-sectional area, material and applied force. Their stresses and strains are therefore equal, giving a ratio of 1:1.
