As an oil well is drilled, each new section of drill pipe supports its own weight and that of the pipe and drill bit beneath it. calculate the stretch in a new 6.00 m length of steel pipe that supports 3.00 km of pipe having a mass of 20.0 kg/m and a 100-kg drill bit (in mm). the pipe is equivalent in stiffness to a solid cylinder 5.00 cm in diameter.
