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 $F$

Answer 1

Answer: (A)

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