NEET · Physics · STD 11- 8. mechanical properties of solids
Let a wire be suspended from the ceiling (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 :
- A Zero
- B \(2 W / A\)
- C \(W / A\)
- D \(W / 2 A\)
Answer & Solution
Correct Answer
(C) \(W / A\)
Step-by-step Solution
Detailed explanation
