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.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever

its c i just checked it

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
