A wire is suspended from the ceiling and stretched under the action of weight F suspended from its other end. The force exerted by the ceiling on it is equal and opposite to the weight.

A

Tensile stress at any cross section A of the wire is `F//A`.

B

Tensile stress at any cross section is zero.

C

Tensile stress at any cross section A of the wire is 2 `F//A`.

D

Tension at any cross section A of the wire is F.

Text Solution

Verified by Experts

The correct Answer is:
A, D
Tensils stress `("force")/("area") =(F)/(A)`
Tensils = applied force = F
