The most common type of pulley is the fixed pulley. A fixed pulley is attached to a fixed point and does not move. It simply changes the direction of the force applied to it. For example, if you use a fixed pulley to lift an object, the force you apply will be pulling down on the rope, but the object will be lifted up.
Another type of pulley is the moveable pulley. A moveable pulley is not attached to a fixed point and can move along with the object being lifted. This type of pulley reduces the amount of force required to lift an object. For example, if you use a moveable pulley to lift an object, you will only need to apply half as much force as you would if you were using a fixed pulley.
Finally, there is the compound pulley, which is a combination of fixed and moveable pulleys. Compound pulleys are used to lift very heavy objects. They reduce the amount of force required to lift an object even more than moveable pulleys.
In a garage, you might find several different types of pulleys, depending on the tasks that are typically performed there. For example, a fixed pulley might be used to lift heavy objects, such as a car engine. A moveable pulley might be used to lift lighter objects, such as a lawn mower. A compound pulley might be used to lift very heavy objects, such as a boat.
The pulleys that are in your garage will likely depend on the specific needs and hobbies of the people who use it.
