Is a crane a type of a pulley?
A crane is a movable pulley
What simple machine is Fixed or movable?
A pulley is a simple machine that can be either fixed or movable. A fixed pulley is anchored in place and changes the direction of the force applied, while a movable pulley moves with the load and reduces the amount of force needed to lift it. Both types are used to lift heavy objects more easily.
What arrangment of movable and fixed pulleys would give a mechanical advantage of 3?
To achieve a mechanical advantage of 3 using pulleys, you can use a combination of fixed and movable pulleys. One common arrangement is to have one fixed pulley and one movable pulley. In this setup, the load is attached to the movable pulley, which is supported by a fixed pulley above it. The user would pull down on the rope, effectively distributing the weight of the load over three segments of rope, resulting in a mechanical advantage of 3.
Why does a movable pulley have a mechanical advantage of 2?
A movable pulley has a mechanical advantage of 2 because it allows the effort force to be applied in a way that supports both the load and the weight of the pulley itself. When lifting a load with a movable pulley, the rope is effectively divided into two segments that bear the load's weight, which means you only need to exert half the force required to lift the load directly. This configuration reduces the input force needed to lift heavy objects, thereby providing a mechanical advantage of 2.
How do movable pulleys increase machanical force?
Movable pulleys increase mechanical advantage by allowing the load to be shared between multiple segments of rope, effectively reducing the amount of force needed to lift a weight. In a movable pulley system, as you pull down on the rope, the pulley moves up, allowing you to lift the load with less effort. This configuration divides the weight of the load, making it easier to lift. Therefore, while the distance you pull the rope increases, the force required to lift the load decreases.
How can a fixed pulley and movable pulley be put together?
With the string from the movable pulley
Is a movable pulley is fixed at all points?

What are 2 different kinds of pulleys?
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)
Is a crane a type of a pulley?
A crane is a movable pulley
Unlike a fixed pulley a movable pulley the?
multiply
What is a compound pulley?
a coumpound pulley is when there is a fixe pulley and movable pulley working together
What is compound pulley?
a coumpound pulley is when there is a fixe pulley and movable pulley working together
What is the difference between a fixed pulley and movable pulley?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.
What kind of pulley is a fishing pole?
Single movable pulley
What is the advantage of using a movable pulley?
A movable pulley reduces the amount of force needed to lift an object because it changes the direction of the force. When using a movable pulley, the load is shared between the pulley and the user, making it easier to lift heavy objects.
What uses a movable pulley?
nothing
When can be movable pulley be used for?
elevators
