Asked by Erich
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?

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
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
