Who invented the pulley?
Archimedes was an ancient Greek scientist known to have invented the pulley as well as other simple machines such as the lever. The biggest advantage of a pulley system is that it can double the strength applied to lift the weight. Other names for pulleys include a drum or a sheave.
What are some examples of a Pulley?
Pulley Facts for Kids. Examples in our everyday world include blinds, garage doors, and even a flagpole. These simple machines have been around for thousands of years. The origin is not quite known but some historians believe that Mesopotamians used this simple machine to life water as long ago as 1500 BF.
What is a moveable pulley?
Next, a moveable pulley has an axel that has the liberty to move and is also used to redirect forces. In other words, with a mechanical advantage of 2, with one end of a rope anchored, a moveable pulley is able to attach a double amount of force to an object.
What is a compound pulley?
Finally, a compound pulley is a combination of a static and moveable pulley. An example of a compound pulley is a block & tackle.
What are the different types of pulleys?
Types of Pulleys. The three main types include static or fixed pulley, moveable pulley, and compound pulley . A static pulley is the most simple and has an axel that is stationary. In other words, it uses this axel and a wheel to redirect the force of a rope.
How to make a pulley?
So to make a basic pulley, all you need to do is loop a rope over some sort of wheel and axle. Two pulleys can be used to create a simple belt and pulley system, in which a belt is looped between the two pulleys.
How does a pulley work?
As I mentioned previously, the simple pulley is a wheel and axle with a rope or belt looped around it. As the rope is tugged, the pulley turns. The force on the rope travels around the pulley to the other end of the rope, so the pulley changes the direction of the force. If you were to attach a weight to one side of a rope, loop it around a pulley, and pull down on the other side of the pulley, the weight would lift up! It's very simple. The direction of the force of your tug is changed from down to up.
How to drive a pulley on the same plane?
To An Axis on the Same Plane: If you want to use a pulley system to transmit rotation from a driving axis to another axis on the same plane, you'll need to feed the belt around two idler pulleys and onto the pulley you want to drive. The idler pulleys basically allow the belt to "bend" at a given angle to get to the driven pulley on the other side. This system can work with most belts and cable, although it will not work with timing belt pulleys because they aren't very thick, and the idlers contact the side of the belt.
What is a belt and pulley system?
A belt and pulley system is one of the simplest types of pulley systems. As I described before, it contains two pulleys, one driving the belt and one driven by a belt. Belt drives can take many different forms; in tank treads, band saws, and sewing machines. Below are the four most common types of belts.
How to invert a cross belt drive?
Cross Belt Drive: The simplest method to invert rotation is by "flipping" one side of your belt so that the belt loop creates a figure 8. This is commonly seen in cable drive mechanisms. However, this technique cannot be applied to chain or belts with specific profiles, like V-belts or timing belts, because chains are not flexible enough, and the pulley would interface with the outside face of the belt. This technique may be tricky if the pulleys are close together.
Why are pulleys used in motors?
Belts and pulleys can be used to transmit power over larger distances and in constricted spaces, which is one advantage they have over gears. Because most pulleys are driven by the friction between the pulley and the belt, if a part of a mechanism jams, then the belt transmitting power will slip on its pulleys instead of stalling the motor.
What is a pulley used for?
From tank treads to bike gears to fishing lines, pulleys are used all over the place when it comes to mechanical transmissions. All types of pulley mechanisms consist of some sort of flexible belt (chain, cable, rope, etc.) turning around the circumference of a wheel, and pulleys can be incredibly useful in a variety of situations.
How to rig a pulley?
To rig a simple pulley, you’ll need to first secure the fixed pulley to an anchor point. This will aid in providing a sturdy base. Then select the best rope for mechanical cables rated for the weight you’re lifting . You’ll need to make sure this rope fits the grooves on your pulley wheel.
How does a pulley work?
Pulleys make a job easier. As one of the six simple machines, a pulley works through the combination and association of a grooved wheel that pivots around an axel. With the help of a rope threaded through the grooves, a pulley can lift heavier weights will less force exerted.
How to attach a rope to an overhead anchor?
Start the process by attaching the fixed pulley to the overhead anchor point. Once these points are sturdy, the rope that you ran through like above will be run through the bottom of the upper pulley and through the wheel of the lower pulley. Loop the rope through the fixed pulley again and then attach the rope to your desired object.
What is pulley system?

What is compound pulley?
A compound pulley system will reduce the weight needed to move an object. This system, in its simplest form, is described as a double pulley system with one fixed pulley anchored overhead and another attached to the load moving it up as needed.
Do pulleys reduce force?
Simple pulley systems don’t reduce the force needed to lift the object, but it does give you the ability to apply force in a different direction.
