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.
