A wire of length $L$ and radius $r$ is made of a material with Young's modulus $Y$ . If a force $F$ is applied, stretching the wire by an amount $Δ L$ , what is the stress in the wire?

Options:

Answer:

Solution:

Stress is defined as the restoring force per unit area. For a wire under tension, the force is $F$ and the cross-sectional area is $π r^{2}$ . Therefore, stress $= \frac{Force}{Area} = \frac{F}{π r ^{2}}$ .
