A vertical steel cable of diameter 54 mm and of length 18 m supports a weight of 1500 N attached to its lower end. Calculate:
a the tensile stress in the cable
b the extension of the cable
c the elastic energy stored in the cable

For parts b and c, you need the Young's modulus of steel.

Young's modulus of steel varies according to the type of steel, but is typically around 200 GPa.
