A pulley overcomes static friction, which is the friction between the surface of the pulley and the rope or belt moving over it. This allows the pulley to rotate smoothly and lift objects with less force required.
When a pulley break and falls to the floor what change in force is this called?
This is called a sudden release of tension or force. The force that was once supporting the load is no longer present, causing the pulley to break and fall to the floor.

This happened to me and I called my dad for help. He told me that it would be really stupid to fix on my own, and usually he will fix anything.
The problem is that garage doors have very strong springs that will injure or kill and unprofessional. He told me that it would be better to just get someone to do it who knows how, and he even offered to pay.
Just go through the yellow pages and call everyone who does garage repair. Most people wanted 150, but I got someone for 75 who did a great job.
How do pulleys works in a motor car?
They allow for a mechanical link from the engines crankshaft, to other components of the vehicle. (Via the drive belt)
They also allow for variable ratio's, to allow for items attached to the belt to turn at different speeds then that of your crankshaft.
Example:
Your crankshaft turns at 1000RPM,
Your alternator turns at 2000 RPM.
This is achieved by having a smaller pulley on your alternator then what is on your crank.
You can also have idler pulleys, and these merely provide a means to effectively route the drive belt.
