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.
(i) Tensile stress at any cross-section A of the wire is $\frac{\mathrm{F}}{\mathrm{A}}$.
(ii) Tensile stress at any cross-section is zero.
(iii) Tensile stress at any cross-section A of the Wire is $\frac{2\mathrm{F}}{\mathrm{A}}.$
(iv) Tension at any cross-section A of the wire is F.
