Chapter 5, Problem 35PE
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. The pipe is equivalent in stiffness to a solid cylinder 5.00 cm in diameter.

As an oil well is drilled, each new section of drill pipe supports its own weight and the weight of the pipe and the drill bit beneath it. Calculate the stretch in a new 6.00-m-long steel pipe that supports a 100-kg drill bit and a 3.00-km length of pipe with a linear mass density of 20.0 kg/m. Treat the pipe as a solid cylinder with a 5.00-cm diameter.
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 millimeters, in a new 6.5 m length of steel pipe that supports 3.00 km of pipe having a mass per length density of 23 kg/m and a 120-kg drill bit. The pipe is equivalent in strength to a solid cylinder 5.00 cm in diameter with Young's modulus of 2.10 × 1011 Pa.
A 557-N force is applied to stretch a cable, 66-m long and has a cross-sectional area of 2.8 mm^2. Young's modulus for the cable is 1.0 × 10^11 N/m^2. How far does the cable stretch?
