Same tension is applied to the following four wires made of same material. The elongation is longest in
- A Wire of length and diameter
- B Wire of length and diameter
- C Wire of length and diameter
- D Wire of length and diameter
Answer & Solution
Correct Answer
(A) Wire of length and diameter
Step-by-step Solution
Detailed explanation
The Young's modulus (E) is a property of the material that tells us how easily it can stretch and deform and is defined as the ratio of tensile stress (σ) to tensile strain (ε). Y=FAdll⇒dl=lπd2×4FY As in our case, value of 4FY will be constant.…
