1.	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.
Answer» 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. Solution :At every cross section for the wires SUSPENDED from CEILING force exerted is F. Now Stress = `("Tensile force ")/("Area") = F/A` `THEREFORE` Tensile force T = Force F exerted.
