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

A motor pulley car science project typically involves attaching a small motor to a car chassis, with a pulley system to drive the wheels. By adjusting the size of the pulley, you can explore how different gear ratios affect the speed and torque of the car. This project demonstrates basic principles of mechanical advantage and gear systems in a hands-on way.
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 "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.
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.
Oh, dude, the plural of pulley is "pulleys." It's like when you have one pulley, and then you get a bunch more, and you're like, "Hey, look at all these pulleys!" So yeah, it's just adding an "s" at the end, nothing too crazy.
a coumpound pulley is when there is a fixe pulley and movable pulley working together
