A wire of length L and radius r is loaded with a weigth Mg. If y and `sigma` denote the Youngs modulus and Poisson's ratio of the material of the wire respectively. Then the decreases in the radius of the wire is given by

A metallic wire of length and diameter 3 m and 0.001 m respectively is stretched by a load of 10 kg.Young's modulus and Poisson's ratio of the material of the wire are respectively 20 times 10^10 N.m^-2 and 0.28 . Calculate the decrease in the diameter of the wire. ( g=9.8 m.s^-2 )

A wire is stretched such that its volume remains constant. The Poisson's ratio of the material of the wire is

A wire of length L and area of cross-section A, is stretched by a load. The elongation produced in the wire is I. If Y is the Young's modulus of the material of the wire, then the torce corstant of the wire is

A wire of length L and area of cross-section A, is stretched by a load. The elongation produced in the wire is I. If Y is the Young's modulus of the material of the wire, then the force constant of the wire is

A metallic wire of length and diameter 300 cm and 0.1 cm. respectively is stretched by a load of 10 kg. Young's modulus and Poisson's ratio for the material of the wire are 20 times 10^11 dyn.cm^-2 and 0.26 respectively Calculate the decrease in diameter of the wire.

There is no change in the volume of a wire due to the change in its length on stretching. The Poisson's ratio of the material of the wire is
