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.

What are some examples of block and tackle pulleys?
Block and tackle pulleys can be found in various applications. Some common examples include sailing rigging on boats, theater rigging for stage productions, and construction projects for lifting heavy materials.
What is an example of a compound pulley?
An example of a compound pulley system is a crane. This system involves multiple pulleys connected in multiple systems to provide mechanical advantage for lifting heavy loads. By distributing the weight across various pulleys and ropes, a compound pulley system makes it easier to lift heavy objects.
idle pulley is a pulley on an engine that does not drive any accesories ,such as water pump or alternator. it is put there to route the belt so as the belt will not hit or rub on other parts or accesories
What is an example of a block and tackle pulley?
A block and tackle pulley system consists of one fixed pulley and one moving pulley working together to lift heavy loads with less effort. For example, a flagpole typically uses a block and tackle pulley system to raise and lower the flag.
What is moat or pulley system of irrigation?
moat irrigation system is a manual type of irrigation in which the water is drawn from a well and the plants r irrigated
What is the function of a pulley?
1. To change the direction of a cable control. 2. Multiple pulleys will decrease the force required to lift or pull a weight. 3. Used to control tension and slack in a belt drive. People use Archimedes' invention of the pulley to pull and lift heavy things easily. Pulleys are made of ropes, handles, and usually metal.

How do you install a Kenmore dryer idler pulley assembly?
As Kenmore appliances are re-branded models manufactured by several different companies, there is no one right answer to your question. However, I recently faced the same problem after the belt broke in my Whirlpool-made Kenmore dryer. The trouble is that the idler assembly in my model (110.86427110) is held in place by tension only, so when the belt breaks in this model, the idler assembly will most likely be found laying in the bottom of the unit. The assembly is a simple looped-back strap of spring steel with a plastic wheel on one end, and for a while I was unable to figure out how it would have been attached to work correctly. If your model is similar to mine, you should find two slots in the sheet metal directly in front of the motor. Tuck the plain end of the idler strap from the right into the larger, leftmost slot. You'll find that when you push the idler wheel end upwards and towards the right in order to fit the drive belt, the resulting pressure keeps the assembly in place.
a pulley that is attached to the resistance and moves with it
A pulley is based on a rope and roller system, often called a drum, which uses the rope as the attachment to the object to be raised or moved. Pulleys provide high motive strengths applied to the load, and enable control of the movement of the object.
Examples of Pulley:
The best known and most advanced example of the powered pulley is the crane, which also includes lateral movement capabilities and 'reach', providing high levels of efficiency on site.
Hand powered or cranked pulleys are usually used for low level weights, often used on building sites or in workshops as load managers.

How do you build a pulley for a science project?
- Work Gloves
- Wire Clothes Hangers
- 20 To 50 Feet Ropes
- Buckets
- Old Bike Wheels
- Pliers
Step 1:
Get an old wheel from a bicycle.
Step 2:
Remove the tire from the wheel.
Step 3:
Bend a coat hanger into a U shape that extends from the axle on one side of the wheel, around the outside of the wheel and to the other axle. The U should leave a 3-inch gap at the rim, and 4 inches of extra wire at each axle by which to attach it.
Step 4:
Use pliers to wrap the ends of the coat hanger tightly around the axles. Make sure the wheel is still able to spin.
Step 5:
Use the pliers to twist a loop into the gap of wire at the rim.
Hanging the PulleyStep 1:
Select a strong beam, rafter or branch to hang the pulley from.
Step 2:
Attach the pulley to the beam by running a cord or rope around the beam and through the loop in the support wire.
Step 3:
Run a cord or rope around the rim of the wheel and underneath the support wire. This is the lifting rope, and it will need to be twice as long as the height you plan to lift.
Step 4:
Make sure the lifting rope can roll easily around the wheel without snagging on the support wire.
Using the PulleyStep 1:
Tie the item to you the end of the rope - this is the load side. Attach a bucket to the load side of the lifting rope for lifting large items.
Step 2:
Tie a knot before pulling.
Step 3:
Pull on the end of the rope until the load reaches the desired height. Keep on lifting the rope to avoid dropping the load.
Kitchen ceiling-hung clothes airer/drier. http://www.sheilamaid.com/ A Sheila's Maid is a traditional laundry airer that can still be found and used in British households for over 100 years. It dries your clothes by using a pulley to raise the Sheila Maid to ceiling height where rising warm air dries your clothes. The Sheila's Maid is often constructed of pine slats fixed at either end with cast iron designed hangers to support the equidistant slats which are used to dry the laundry items
The block and tackle (or pulley system) was brought to us by Archimedes (287BC - 212BC) in Greece, but neither Archimedes, nor any who wrote about him and his extraordinary work dated the invention.stupid answer
Input Distance is the distance the input force acts through.
Static force refers to the force acting on an object when it is stationary or at rest. It is the force that must be overcome to initiate movement or to keep the object in place. Static force does not change as long as the object remains still.
A block and tackle is a system of two or more pulleys each enclosed by a housing with a rope or cable threaded between them.

How is a lever different from a pulley used with ropes?
A lever and a pulley are different. They are both simple machines that have been around for over two thousand years and described in detail by a Greek named Archimedes.
How do you remove an engine pulley from a craftsman 917.252610 mower?
Pulleys are held on to shafts by either a bolt in the bottom or a set screw in the side, loosen them and use a gear puller.
Certainly - however, sometims the 3rd space can only accomodate a golf cart, none the less, it is still a car space and counts as 3 car garage.
