Pulleys
A pulley is a mechanism composed of a wheel on an axle or shaft. A rope, or cable usually runs over the wheel and inside the groove. Pulleys are normally used to change the direction of an applied force to make the work easier. It is one of the six simple machines.

Why are pulleys so important to every day life?
pulleys are important in everyday life because we needed to lift up heay weight objects that a human cant do in their everyday life so pulley is a very important simple machines to humanity.
Why did Archimedes make the pulley?
because king heroin challenged Archimedes to bring a ship to the beach single handedly. so archimendes thought and thought then came up with the pully
What is the function of the idler pulley on cars?
Idler pulleys are used to maximize belt contact with other pulleys and to redirect belt around other parts that might interfere with the belt.
Firearms may contain cams and levers, but the firearm itself is not considered a pulley.
How do we keep the dryer belt from slipping of the pulley?
Make sure the cable is Secure, and or you can push harder than usual.
More information of uses of pulley?
Pulley systems are used in the real world to lift large masses onto tall heights. You might have seen the workers repairing the roof of a house and using the pulley system to lift their tools or materials to the roof. A pulley is an example of a simple machine.
The pulley system consists of one or more pulleys and a rope or a cable. The number of pulleys used may increase or decrease the mechanical advantage of the system. Generally, the higher the mechanical advantage is, the easier it is to lift the object that is being lifted.
Overall, no matter how easy it is to use the pulley system, the system itself is not very efficient due to the force of friction. For example, one has to pull two meters of rope of cable through the pulleys in order to lift an object one meter.
The applet below illustrates just that. Select the number of pulleys and drag the mouse to see the inefficiency of the system.
How do you take the pulley off an alternator?
Over the years I have ruined several an Alternator pulleys because I refused to spend the money to buy an Alternator Pulley Removal Tool.
I finally learned the hard way, and for a long time have used the proper removal tool; no more ruined pulleys!!!!
Due to the design of Alternator Pulleys, an ordinary "Gear Puller" cannot get a "proper grip" on the pulley flange, and the force necessary to overcome the friction of the force-fit of the pulley to the shaft results in damage to the pulley.
Go to any auto parts supply store and buy an Alternator Pulley Removal Tool. They don't cost much, and are well worth it in time saved, and the cost of replacement pulleys. Then just follow the instructins that come with the tool and you should have not trouble. Good luck!
1996 Jeep Cherokee Tensioner Pulley?
There is no tensioner pully. The Power Steering pump has a moving bracket that adjusts the belt tension. It has a long adjustment bolt. You have to remove the air cleaner and housing to reach it successfully.
Funny, mine has a belt tensioner pulley under the power steering pump, which is tightened by a long adjustment bolt. So does every other 1996 Cherokee I've worked on!
How do you pull a damper pulley from a Chevy 350?
If you are just removing the pulley, Then just remove the bolts that hold it on being sure to remove the bolt that is in the middle of the pulley too. Then take a hammer and knock it off.
Pulleys are typically made out of materials such as metal, plastic, or ceramic. The choice of material depends on factors like the load capacity, environment, and intended application of the pulley. Metal pulleys are commonly used for heavy-duty applications, while plastic pulleys are preferred for lighter loads and quieter operation.
How does a pulley change speed?
A pulley changes speed by dividing the distance that needs to be moved by the force applied. When a smaller pulley is used, the speed increases because the force is concentrated over a smaller distance. Conversely, a larger pulley decreases speed by spreading the force over a larger distance.
A simple pulley is a type of machine consisting of a wheel with a groove in its rim, along with a rope or belt that fits into the groove. It is used to lift or move objects by applying force through the rope. Simple pulleys can change the direction of the force applied to move objects more easily.
If the bottom pulley locks up what does that mean?
You are broken on the bottom end. Could be a rod, bearing or other broken part.
