simple? gravity.. but since you said machine, I would guess you are referring to the pulley? basically you are offsetting the force of gravity by 'sliding' down the cable.
a simple machine that pushes and pulls is like a close line you push it and pull it back
A clothesline is a simple machine that falls under the category of pulleys. Some other types of simple machines include wedges and levers.
Actually, it is in the name and pretty simple. It is surprisingly called the International Date Line
The coccyx is broken in two pieces along a straight line
A flyover machine is a conveyor belt that can be loaded and the transport items to another location. In many auto manufactures they use this machine to install heavy car parts in conjunction with an assembly line.
A clothes line uses a pulley, which is an ingenious simple machine. More complex uses of pulleys have certainly played a role in science and technology.
need a line for a FAX MACHINE
they used the water
A simple machine is a closed mechanical system that changes the direction and/or the magnitude of a force using only the work and energy supplied by the operator. A lever is an example of a simple machine, and so is a pulley. . A clothes line - the kind that has a loop of cable bound by one pulley at each end - is a simple machine. As you pull one side of the loop toward you, the other side of the loop moves away from you, thanks to the action of the pulleys. Since you are doing all the work (there is no motor or other source of energy), this reversal of direction qualifies as a simple machine.
Sewing a straight line has to be done very carefully. I recommend using a machine, and lining up the edge of your project with one of the guide lines along the base of the sewing machine. You may want to practice on a piece of paper beforehand.

A line of machines and workers in a factory that a product moves along while it is being built or produced. Each machine or worker performs a particular job that must be finished before the product moves to the next position in the line
