What is a block and tackle used for?
Block and tackle refers to a rope threaded through a series of pulleys to provide mechanical advantage, and it is used to lift heavy 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.
How does a pulley help you do work?
A single pulley is one of the "simple machines" in physics, and makes work seem easier by redirecting the action required to work along with gravity. For example, you can lift something by by pulling down on a rope.<br><br>Multiple pulleys make work even easier, but you need to do more of it: running a rope through six pulleys will make the load seem 1/6 as heavy, but you'll have to pull the rope six times as far.<br><br>A handy guide to the simple machines is here: http://teacher.scholastic.com/dirtrep/Simple/pulley.htm<br>
How pulleys work?
Pulleys have a rope that goes over the top of the pulley that is when pulled used to raise what ever you want raised.
How does a pulley make work easier?
1) it doesn't. Work = force x distance. So a pulley that reduces force will also increase distance -but -it can reduce the force needed to move somethingthus making life easier.Answer:It depends on the number of pulleys and their arrangement. A single pulley does not change the force required to lift something. But, other pulley arrangements do. Four pulleys can be arranged into a thing called a block & tackle that can divide the force required to lift something by four. But, the rope must be extended four times as long to do this.
How did they get the top stone on top of the upright stones at Stonehenge?
They used a series of pulleys and rope,and a lot of man power!

Will the force applied to lift a brick reduce if you use pulleys?
yes, pulley will help IF not the if YOU USE COMBINE TWO OR MORE PULLEYS. Yes, using a pulley or a system of pulleys will reduce the force needed to lift a brick (or anything). HOWEVER the distance that the rope (or whatever effects the pulley system) has to now travel further so that the energy required to lift the brick through an equal height is always the same.
What kind of a simple machine is a rope?
ropes can be in pulleys

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.
How do you make a pulley project for fourth grade?
To make a pulley project for fourth grade, you can use a simple setup with a pulley, rope, and a small lightweight object to lift. You can demonstrate how the pulley makes it easier to lift the object by distributing the force needed over multiple ropes. Have the students experiment with different numbers of pulleys and ropes to observe the differences in lifting efficiency. Encourage them to think about real-life applications where pulleys are used, such as in elevators or construction sites.
What do you use a simple fixed pulley for?
To lift things up more easily. Duh. You see, if you get more and more pulleys and keep putting them on the same rope, your load would become easier to lift as you added more. In fact, if you had a rope that was strong enough, one could easily lift a Black Rhino using 4,993,374 pulleys. This is just a theory, however. There is no one rope strong enough to lift that. And, nobody will ever try to do that. We have elevators for a reason, folks. The elevator pretty much ruined the use of a pulley. Another thing you could use the pulley for is to make a movie set that is set in a place in which you would need pulleys. For example: a place without elevators or pistons and a lot of heavy rhinos that need lifting. One last use for the pulley is to hang it up in an elevator as a symbol of uselessness. It can be used to make a statement. The statement may vary depending on where the elevator is located, the weight limit of the elevator, etc. One good way to be very ironic is to take 4,993,374 pulleys (the amount it takes to lift a rhino), hang them all up in the elevator with rope and everything, and make sure that the weight limit of the elevator is under 2,500 lbs. If you live in an industrial area, you are out of luck. This works best in an elevator that is used by lots of people daily, but is in grave need of an upgrade. In short, use your pulley to lift heavy things. Like rhinos.
What is the simple machine used to hoist the flag?
Rope and pulley.
Can the number of pulleys affect the amount of force to lift a heavy objects to a high place?
Increasing the number of pulleys divides the force required to lift up a heavy object; increasing the number of pulleys decreases the force needed by the person (or motor) pulling the first end of the pulley system. However, it is important to know that it does not affect the total work needed to lift up the object. As the force is decreased, the distance of rope needed increases to compensate for a conserved amount of work required for the load to be lifted.
