What is both fixed and movable pulley?
Compound System In a compound pulley system, there is both a moveable pulley as well as a fixed pulley. This means that not only does the load “feel” lighter, but you can also change the direction of the force.
What is the difference between a pulley and a fixed pulley?
A fixed and a movable pulley are both used to lift heavy objects. 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.
What are examples of fixed pulleys?

Here are some fixed pulley examples that we come across in everyday life….Fixed Pulley Examples:
- Water well.
- Flagpole.
- Window blinds.
- Adjustable Clothesline.
- Pulley Lighting.
- Motor Pulley.
- Anatomical Pulley.
What are the 2 types of pulleys?
Among the pulley simple machines, there are three different types of pulleys:
- Fixed pulleys are a very common pulley. These pulleys are secured to a single spot.
- Movable Pulleys are yet another type of pulley.
- Compound Pulley Systems are a combination of both movable and fixed pulleys.
What is single fixed pulley?

A pulley is a metallic disc with a grooved rim and a string is passed around the groove at the rim. A pulley which has its axis of rotation fixed in position is called a single fixed pulley. It is used to change the direction of effort.
What is the difference between single fixed pulley and movable pulley?
A single fixed pulley is defined as a pulley with its axis of rotation fixed in place. It’s used to shift the effort’s direction. Whereas, a movable pulley is one that can move up and down and is connected to a ceiling or another object by two lengths of the same rope.
What type of work is done by a fixed pulley and a movable pulley?
A fixed pulley changes the direction of the force on a rope or belt that moves along its circumference. Mechanical advantage is gained by combining a fixed pulley with a movable pulley or another fixed pulley of a different diameter.
Does a fixed pulley move?
The fixed pulley is a pulley that is attached to a structure and does not move. It’s main purpose is to change the direction of the force needed to lift a load. A force is exerted downward in order to lift the load upward.
Where are fixed pulleys used?
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.
- Exercise Equipment.
- Theatre Curtains.
- Construction Equipment.
- Flagpoles.
- Blinds.
What are the two types of pulleys?
Why does a movable pulley make work easier?
The mechanical advantage of a moveable pulley is 2. This means that a moveable pulley will halve the required force needed to move any object attached to it. This occurs because in a moveable pulley one end of the rope is stationary, which means it absorbs some of the force needed to move the object.
How does a fixed pulley work?
A fixed pulley changes the direction of the force you exert by pulling, so you can pull down to move an object up.
