An 1567 kg car, being lifted at a steady speed by a crane, hangs at the end of a cable whos radius is .0084. The cable is 5m in length and stretches by .0081 becuase of the weight of the car. What is young's modulus for the cable?

Answer 1

Use this formula:
E*(delta L)/L = (F/Area)

E is the Young's modulus you want to solve for
F is the car's weight, in Newtons, M g
Area = pi* R^2
delta L = 0 0081 m
L = 5 m
