Question

A brass wire 1.8m long at 27°c is held taut with little tension between two rigid supports. If the wire is cooled to a temperature of -39°c , what is the tension developed in the wire if it's diameter is 2mm? coefficient of linear expansion of brass is 2×10^-5c-1. Young`s modulus of brass is 0.91×10^11​
