A high-speed lifting mechanism supports a 880-kg object with a steel cable that is 39.0 m long and 4.00 cm2 in cross-sectional area.
(a) Determine the elongation of the cable.
__________ mm
(b) By what additional amount does the cable increase in length if the object is accelerated upwards at a rate of 2.7 m/s2?
______________ mm
(c) What is the greatest mass that can be accelerated upward at 2.7 m/s2 if the stress in the cable is not to exceed the elastic limit of the cable, which is 2.2 ? 108 Pa?
_____________ kg
