Question

A high-speed lifting mechanism supports a(n) 880-kg object with a steel cable that is 32.0 m long and 4.00 cm2 in cross-sectional area (a) Determine the elongation of the cable. (Enter your answer to at least two decimal places.) 0.0038328X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully (b) By what additional amount does the cable increase in length if the object is accelerated upwards at a rate of 3.4 m/s2? 0.0051626X Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully (c) What is the greatest mass that can be accelerated upward at 3.4 m/s2 if the stress in the cable is not to exceed the elastic limit of the cable, which is 2.2 x 108 Pa? Enter a number differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully kg
