How much force is used to lift 100 lbs using 3 pulleys?
30
How are pulleys used in everyday life?
pulleys are used in everyday life in many different situations and mechanisms. This is understandable because pulleys when used and set up correctly can lift or move a weight that is much greater than the force exerted upon the pulley. they are used in crane systems.
Does a pulley use less force?
There are a variety of different designs for pulleys, depending upon what you need to do with them. A pulley can be used to change the direction of a force without changing the amount of force that you apply, but there are also pulleys that do reduce the amount of force you have to use to lift something.
What are facts about the pulley?
Pulleys are used to lift objects
Is a block and tackle an example of a rotational force transformer?
is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift or pull heavy loads.

Where else are pulleys used?
assuming that your question is what jobs are pulleys used for... then the answer is any job that you need to lift something that is heavy. The pulley give a mechanical advantage when used together with other pulleys to apply more force to move the object

What jobs did the pulley do?
A pulley is a wheel with a groove on its edge for holding a rope or cable. pulleys are usally used in sets desinged to reduce the amount or force needed to lift a load.
What is 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.
A set of pulleys is used to lift a piano weighing 1000 newtons the piano is lifted?
You need to know the capacity of the pulleys. The pulleys need a total power of over 1000 newtons, if they do then you should be fine.

What jobs use combination pulleys?
Tree trimming uses combination pulleys. Also combination pulleys are used to lift engines out of cars to work on them. Some construction sites use them in places they cannot get a crane.
How can pulleys be used to reduce the force in lifting up an object?
They convert distance into force. So putting a pulley on a load would result in you having to haul up twice as much rope, but lifting about half of the weight of the load. Multiple pulleys increase rope length and further decrease force required to move the load.
