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

Question

A wire is suspended from the ceiling and stretched under the action of a 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

Tensila stress =( text force / text area )=(F/A) Tension = applied force =F

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

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

Tensile stress at any cross section is zero

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

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

Tensila stress $= \frac{force}{area} = \frac{F}{A}$
Tension $=$ applied force $= F$

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

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

Tensile stress at any cross section is zero

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

Tension at any cross section A of the wire is F

Tensila stress = area force ​=AF​ Tension = applied force =F
