{"ops":[{"insert":"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 8.00-m-long steel pipe that supports a 200000-g drill bit and a 5.00-km length of pipe with a linear mass density of 20.0 kg\/m. Treat the pipe as a solid cylinder with a 8.00-cm diameter."},{"attributes":{"list":"ordered"},"insert":"\n"},{"insert":"A large uniform cylindrical steel rod of density \u03c1 = 8.8 g\/cm3 is 4.0 m long and has a diameter of 5.0 cm. The rod is fastened to a concrete floor with its long axis vertical. What is the normal stress in the rod at the cross section located at (a) 2.0 m from its lower end? (b) 2.5m from the lower end?"},{"attributes":{"list":"ordered"},"insert":"\n"},{"insert":"Two children push on opposite sides of a door during play. Both pushes horizontally and perpendicular to the door. One child push with a force of 20.5 N at a distance of 0.600 m from the hinges and the second child pushes at a distance of 0.650 m. What force must the second child exert to keep the door from moving? Assume friction is negligible."},{"attributes":{"list":"ordered"},"insert":"\n"}]}
