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:NEET 2023 (All India)

Options:

Answer:

Solution:

Longitudinal stress is given by,
$s t r e s s = \frac{f o r c e}{a r e a} = \frac{W}{A}$
In case of ideal wire, stress at each point will be the same and will be equal to $\frac{W}{A}$ .
