The longitudinal strain and lateral strain of a given wire ar `5xx10^(-5)` and `25xx10^(-6)` respectively. The Poisson's ratio is

For a wire, the longitudinal strain is 20xx10^(-3) and the lateral strain is 5xx10^(-3) , then the Poisson's ratio of its material is

If the values of Y and eta for a material are 2xx10^(11) pascal and 8xx10^(10) pascal respectively, then the value of Poisson's ratio sigma will be

The ratio of lateral strain to the longitudinal strain of a wire is called

The ratio of lateral strain to the longitudinal strain of a wire is called

When a wire of length 10 m is subjected to a force of 100 N along its length, the lateral strain produced is 0.01 xx 10^(-3) . The Poisson's ratio was found to be 0.4 . If the area of cross-section of wire is 0.025 m^2 , its Young's modulus is

When a uniform metallic wire is stretched the lateral strain produced in it is beta .if sigma and Y are the Poisson's ratio and Young's modulus for wire, then elastic potential energy density of Wire is
