Topic: Strength of Materials
If the radius of wire stretched by a load doubled, then its Young's modulus will-
- A. Be doubled
- B. Be halved
- C. Become for times
- D. None of the above
Answer: D. None of the above
Explanation: Young's modulus is also known as modulus of elasticity. It is the mechanical property of a material that allows it to withstand pressure and expand with respect to its length. It depends only on the material and not on the geometric dimensions like radius. Hence, it will remain unchanged.
