Let a wire be suspended from the ceilling (rigid support) and stretched by a weight \(W\) attached at its free end. The longitudinal stress at any point of cross-sectional area \(A\) of the wire is:
1 \(W / A\)
2 \(W / 2 A\)
3 Zero
4 \(2 W / A\)
Explanation:
Longitudinal Stress \(=\dfrac{\text { longitudinal Force }}{\text { Unit Area }}\) \(=\dfrac{W}{A}\) (Here \(A\) Cross-sectional Area) Correct option is (1)
