A 12.0 kg mass, fastened to the end of an aluminum rod with an unstretched length of 0.70 m, is whirled in a vertical circle with a constant angular speed of 120 rev>min. The cross-sectional area of the rod is 0.014 cm2. Calculate the elongation of the rod when the mass is (a) at the lowest point of the path and (b) at the highest point of its path.
