A 14.5 kg mass, fastened to the end of a steel wire of unstretched 1.0 m, is whirled in a vertical circle with an angular velocity of 2 rev/s at the bottom of the circle. The cross- sectional area of the wire is 0.065" cm"^(2). Calculate the elongation of the wire when the mass is at the lowest point of its path.
