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 Its equal and opposite to the weight - (a) Tensile Stress at any cross-section A of the wire F/A (b) Tensile Stress at any Cross-section is zero. (C) Tensile Stress at any cross-section A of the wire is 2F / A (d) Tension at any cross-section A of the wire is 2 F.​

Answer 1

Explanation:

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 Its equal and opposite to the weight - (a) Tensile Stress at any cross-section A of the wire F/A (b) Tensile Stress at any Cross-section is zero. (C) Tensile Stress at any cross-section A of the wire is 2F / A (d) Tension at any cross-section A of the wire is 2 F.
