It is a wheel that allows for the vector (direction) of a force to be changed. So if I was pulling down on a pulley, the pulley could turn that into me pulling something up.
it mean that the pulley which is a machine that pull stuff has force that fixed the pulley ":"I THINK:""
pulley I vote for a working volcano complete with dinosaurs around it
you could use motor to do a investigation and it is a object to use in science.

Probably a cog, are you doing PHSchool science?

Well, part of physical science is simple machines and compound machines. The simple machines are the gear, screw, wedge, lever, pulley, and wheel and axle, and inclined plane. A bicycle is a compound machine. It is made up of the wheel and axle, gear, pulley, and lever. so it corresponds with that part of PHYSICAL SCIENCE. Hope this answer helped!!!
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.
A "double pulley" may refer to a two-block (two rope) pulley, or to the arrangement of two separate pulley blocks as a "block and tackle" -- designed to make lifting easier by reducing the necessary lifting force: a smaller force is applied over a greater distance to achieve a mechanical advantage.
A pulley is a type of simple machine, consisting of a wheel with a rope running around it. It changes the direction of the force that is applied to the rope. It is also possible, with the use of multiple pulleys, to use them as a force magnifier.
by seeing how many ropes the pulley has... that is close to the mechannical advantage...or it is it! its a cool trick once you learn it! My science teacher just had us do a project on this!
There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.
