A load of 31.4 kg is suspended from a wire of radius `10^(-3)` m and density `9xx10^3 kg//m^3` Calculate the change is temperature of the wire if 75% of the work done is converted into heat. The Young's modulus and the specific heat capactiy of the meterial of the wire are `9.8 xx 10^(10) N//m^2 and 490 J//kg//K` respectively.

A body of mass 3.14 kg is suspended from one end of a non uniform wire of length 10m, such that the radius of the wire is changing uniformly from 9.8xx10^(-4) m at one end to 5xx10^(-4) m at the other end. Find the change in length of the wire in mm. Young's modulus of the material of the wire is 2xx10^(11)N//m^(2) (mass of wire is negligible)

A 10 kg mass is attached to one end of a copper wire, 3m long and 1 mm in diameter. Calculate the lateral compression produced in it. (Possion's ration is 0.25and Young's modulus, of the metereal of the wire is modulus of the material of the wire is 12.5 xx 10^(10) N//m^(2)) .

Calculate the speed of a transverse wave in a wire of 1.0 mm^(2) cross-section under a tension of 0.98 N . Density of the material of wire is 9.8 xx 10^(3) kg//m^(3)
