The elastic limit and ultimate strength ...

The elastic limit and ultimate strength for steel is `2.48 xx 10^(8) Pa` and `4.89 xx 10^(8) Pa` respectively. A steel wire of 10 m length and 2 mm cross sectional diameter is subjected to longitudinal tensile stress. Young’s modulus of steel is `Y = 2 xx 10^(11) Pa`
(a) Calculate the maximum elongation that can be produced in the wire without permanently deforming it. How much force is needed to produce this extension?
