The stress-strain characteristics of a mining cable that supports an elevator is given. The cable has a cross sectional area of 50 mm?. The elevator is used to carry miners down to a shaft 1 km below the surface. When the elevator is at the surface, the cable extends 1.5 m below the pulley. When the elevator is at the mining shaft at the bottom, the cable extends 1,004 m below the pulley which is the full length of the cable
