The length of a wire increases by 8cm when a weight of 5Kg is hung. If keeping the conditions same the radius of the wire is made doubled, what will be the increase in length?

When a body of mass 5kg is hung from a wire of length 1 m and radius 2mm,the length increases by 0.1 mm, IF the poisson's ratio is 0.4 , what will be the change in the radius of the wire? If the load is reduced to 2kg,how will the radius change?

The radius of a copper wire is twice that of a steel wire. One end of the copper wire is joined with one end of the steel wire and the same tensile force is applied on them . If the length of the copper wire increases by 1% , what will be the percentage increase in the length of the steel wire? Given Young's modulus of steel is twice that of copper.

If the length of the sides of a triangle be doubled, then what percentage of its area will be increased ?

When a load of 10 kg is suspended from one end of a wire of length 1m, it increases in length by 0.1 cm. IF the Poisson's ratio for the material of the wire is 1/3 , then calculate the change in volume of the wire, cross-sectional area of the wire =0.1 cm^2 .

Calculate the change in length of a wire of length 5 m undergoing a strain of 1% of 0.1. IF the area of cross section of the wire is 1mm^2 and the load applied on it is 10 kg then find the ratio of stress to strain.
