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?

  • Physics -

    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
