A 100 kg mass, fastened to the end of a steel wire of unstretched length 1 m, is whirled in a vertical circle with an angular velocity of 5 m/s at the bottom of the circle. The cross-sectional area of the wire is 0.070 cm^2 . Calculate the elongaton of teh wire when the mass is at the lowest point of its path ( Ysteel = 200 GPa ).
