its not to push or pull an object its a simple machine made from a grooved wheel with a rope or cable wrapped around the groove.
So you've got a heavy load, and you want to move it. You might try a simple machine that's the basis of much modern machinery --- a pulley. There are six simple machines: an inclined plane , a lever, a screw, a wedge, a wheel and axle, and a pulley. Basically, a pulley changes the direction of an applied force. Thus, for instance, you can pull on the cable of the pulley, and it will pull a weight.
A pulley, which is derived from the Greek word polos, meaning axis, is a wheel with a groove. A rope, belt, or cable runs inside the groove. That mechanism can be used alone or connected with other pulleys in a pulley system. The greater the number of pulleys in the system, the less force it will take to lift an object.

A fixed pulley is a pulley that is attached to a support. It does not reduce the effort needed to lift the load, but rather changes the direction of the applied force.An example of a fixed pulley would be the rope pulley on a well. This is a fixed pulley because the pulley doesn't move (it is attached to the overhead structure).
well i know 3, fixed pulley, movable pulley and a pulley system (double pulley with fixed and movable pulleys). i guess its basically just the first 2.
Pulley is a noun, as in "the pulley helped lift those pallets over there".
There is a crankshaft pulley, alternator pulley, power steering pump pulley, AC pulley, idler pulley, tensioner pulley, etc.
a coumpound pulley is when there is a fixe pulley and movable pulley working together

Things that might cause a pulley to wobble: The pulley is bent. The shaft the pulley is on is bent. The pulley is mounted crooked.
No, it is not a pulley. A pulley has to half effort.
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.
If you pry up on the pulley with a bar on each side of it and while keeping pressure on the pulley, hit the end of the shaft that the pulley is on with a brass mallet, the pulley will usually break free.

The crankshaft pulley is the lowest pulley on the engine. Looking at the engine from the front which is looking at it from the passenger side fender the crank pulley is on the bottom of the engine and has a pulley with a pulley behind it with teeth on it.
