A steel rod of length 1m and radius 10 mm is stretched by a force 100 KN along its length. The stress produced in the rod Y_("Steel")=2xx10^(11)" N m"^(-2)

A body of mass 1 kg is attached to one end of a wire and rotated in a horizontal circle of diameter 40 cm with a constant speed of 2m/s. What is the area of cross-section of the wire if the stress developed in the wire is 5 xx 10^(6) N//m^(2) ?

An aluminium wire and a steel wire of the same length and cross section are joined end to end. The composite wire is hung from a rigid support and the load is suspended at the free end. If Y_(AL) = 7xx10^(10) N//m^(2) and Y_("steel") = 7xx10^(11) N//m^(2) , the ratio of elongation of aluminium and steel wires is
