That means that if you use a simple machine to apply less force, you need to compensate by applying the force over a larger distance - for example, to lift up a weight or do some other work.

∙ 8y agoIt is an inverse relationship. Force*Distance of input = Force*Distance of output. OrForce of input/Force of output = Distance of output/Distance of input.

How is input force used?
Since we know by conservation of energy that no machine can output more energy than was put into it, the ideal case is represented by a machine in which the output energy is equal to the input energy. For simple geometries in which the forces are in the direction of the motion, we can characterize the ideal machine in terms of the work done as follows: Ideal Machine: Energy input = Energy outputWork input = Fedinput = Frdoutput = Work output From this perspective it becomes evident that a simple machine may multiply force. That is, a small input force can accomplish a task requiring a large output force. But the constraint is that the small input force must be exerted through a larger distance so that the work input is equal to the work output. You are trading a small force acting through a large distance for a large force acting through a small distance. This is the nature of all the simple machines above as they are shown. Of course it is also possible to trade a large input force through a small distance for a small output force acting through a large distance. This is also useful if what you want to achieve is a higher velocity. Many machines operate in this way. The expressions for the ideal mechanical advantages of these simple machines were obtained by determining what forces are required to produce equilibrium, since to move the machine in the desired direction you must first produce equilibrium and then add to the input force to cause motion. Both forceequilibrium and torque equilibrium are applied.
What is the ESPN NBA Trade Machine?
The ESPN NBA Trade Machine is an online service provided on the official ESPN website. The NBA Trade Machine allows users trade players between NBA teams. This allows users to see if the trade they are thinking of is valid and could actually happen in the real NBA in compliance with the NBA's trade rules. There is also an option to share the trade so that you can discuss it with other people.
How did trade in gold and salt lead to Ghana's economic growth?
The Saharan trade extended from the Sub-Saharan West African kingdoms across the Sahara desert to Europe. The Saharan Trade linked such African empires as Ghana, Mali, and Songhay to the European world.
How did the slave trade benefit Europeans?
It's pretty simple. The Europeans just gained wealth off the free labor.
Pokemon can you trade with NPC in Pokemon Black and White?
Not from the start, but if you beat the game you can. There is another way though. In a Castelia City building, on a top floor a man will ask you for a 4-word passcode to access a hidden machine. That passcode is EVERYONE HAPPY SIMPLE CONNECTION If you give this to him he will let you use his relocater. Just go to the title screen and select 'relocater'. Follow the on-screen instructions. * You cannot trade Pokemon back to an older version after trading to a new one!
What is essence of using simple machine?
Simple machines lets you trade force for distance, or the other way around. Or they change the direction of a force.
When you trade distance for force what do you get?
Mechanical advantage
What work easier by trading force for distance?
simple machines

What do you trade to get force to help you lift things with inclined planes?
time and distance.
What is the trade off when using and inclined plane?
More distance, less force
What is the function of a block and tackle?
A block and tackle consists of a system of pulleys with a rope and hook. It is a simple machine which lets you lift a heavy weight more easily. We say it gives you a mechanical advantage,or that it is a force multiplier because it lets you trade a large distance by which you pull the rope using a small effort for a small distance lifting the heavy weight. An example is an engine hoist.
What is the trade off of effort in using simple machines?
The simple machines - a lever for example - are usually designed so that you need less force. In compensation, you need to move the lever for a greater distance. This follows directly from the law of conservation of energy.
What is the trade off with a group of pulleys?
A pulley system is a force multiplier. That means you trade distance for force. You pull the rope a long way to lift the load a short way, but the force you need is reduced.
How do machines multiply force without multiplying work?
Work is the (force)*(distance)*(cosine of angle between force and distance). Therefore if you increase the force but the work remains the same either the distance has been reduced or the angle has changed.
What is long distance trade?
where you trade over a long distance
