A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt.

Examples of Pulley Simple Machines
Wells. Wells are one of the oldest applications that make use of a pulley.
Elevators. One of the most common applications of a pulley mechanism in the engineering domain lies in the construction of elevators.
How do you explain a pulley to a child?
Pulleys are made by looping a rope over one or more wheels. They are often used to lift heavy objects: pulling down on one end of the rope creates an upward pull at the other end. Looping the rope over more wheels increases the upward force.
What is pulley and example?
A fixed pulley’s wheel and axle stay in one place. A fixed pulley changes the direction of the force on a rope or belt that moves along its circumference. A good example of a fixed pulley is a flag pole: When you pull down on the rope, the direction of force is redirected by the pulley, and you raise the flag.
What is pulley short answer? – Related Questions
What are the 3 types of pulleys?
Pulleys consist of a wheel that rotates on an axle—which is a rod through the center of the wheel—and a rope, cable, or chain. There are three main types of pulleys: fixed, movable, and compound.
Why do we use pulleys?
Well, pulleys help us by changing the direction of the force we use to lift an object. Is it easier for you to pull up on a rope or pull down on a rope? By using a pulley, we do not have to pull up on a rope to lift a heavy object attached to it, but instead we can pull down on it.
What are some examples of a pulley simple machine?
Elevators: Elevators utilize a pulley system with a motor.
Where are pulley used?
Pulleys are commonly used in shipping and marine applications, as well as for industrial equipment and heavy machinery. Systems typically use multiple pulleys to increase mechanical advantage as it reduces the force needed to lift or pull the weight.
What are 2 examples of a wheel and axle?

What is the shape of pulley?
Example 50 A pulley has the shape of a uniform solid disc.
What are the parts of a pulley?
The three different pulley parts are a wheel, an axle, and a rope. The advantage of using a pulley is that it both changes the direction and point of application of force, making it much easier to lift weights.
What is the structure of a pulley?
A simple pulley consists of a wheel, often with a groove, attached to a fixed structure. The load is raised by a rope, chain or belt. A compound pulley consists of two or more such wheels, some movable, that allow a person to raise objects much heavier than he or she could lift unaided.
What two parts make a pulley?
A pulley is a simple machine that consists of a rope and grooved wheel. The rope fits into the groove in the wheel, and pulling on the rope turns the wheel.
Why do pulleys make work easier?
How do pulleys make it easier to lift? Pulleys are simple machines that can change the direction of force, making it much simpler for us to move objects. They also increase mechanical advantage when we use multiple pulleys together. This process decreases the amount of force required to lift something up.
What are the two types of pulley?
The following are the types of pulley: Fixed pulley. Moving Pulley. Compound Pulley.
How do you make a pulley?
What is a pulley Grade 5?
A pulley is a simple machine which is used to lift heavy objects. It consists of a wheel that has a grooved track for the rope, chain or belt to move through it.
Which pulley can lift a load faster?
A fixed pulley can only provide you a better direction to lift an object. But a movable pulley helps you to lift an object with half of the effort than the load. Thus, using a movable pulley for the same load effort can be reduced, but this can not happen with a fixed pulley.
How many types of pulley are there?
Answer: There are three types of pulleys, namely, fixed pulleys, movable pulleys, and compound pulleys. Fixed pulleys are those pulleys that are attached to a single point. As the name suggests that this pulley is stationary and is fixed to support like wall or ceiling and the rope/chain passes through it.
How do pulleys lose weight?
A one-wheel pulley allows you to change the direction of the force you have to apply to lift the load by pulling down to lift a load upwards. Similarly, a two-wheel pulley splits the weight equally so that each holds only half the weight, allowing you to lift the same weight with half of the force.
