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.

∙ 12y agoA machine can certainly not produce more energy than the energy that goes into it. Physical laws don't allow this. Read about the Law of Conservation of Energy (for example, in the Wikipedia) - basically, no exceptions have been found to this law.

∙ 7y agoA "machine" in this case is like changing Money.
You can trade one bill for lots of coins, or lots of coins for one bill.
But regardless if you have coins or a bill, your buying power stays the same.
It's the same with the machine.
There's a set amount of effort that goes into the machine.
You can trade that effort either for distance or for strength, but you can't get both unless you input more effort.
Answer
Not at the same time, because as distance increases, force decreases, and as force increases, distance decreases. But a machine can increase force by decreasing distance and increase distance by decreasing force.

∙ 13y agoI suppose you want the machine to produce more energy than is put into the machine. This is not possible. For more information, do some reading on "Conservation of Energy".

The force is found by multiplying the mass of an object by the velocity at which it travels?
That is how you calculate thrust. FV=T Force, Velocity, Thrust.
In which direction should you apply a force if you want to do the greatest amount of work?
It depends on the kind of work you want done and whether you're using any simple machines. In case you aren't using any simple machines and you are applying force directly, it is best to apply force in the direction of motion desired.
How much does a block and tackle pulley system multiply the effort force?
4 (:
What is a system of pulleys designed to multiply the effort force called?
moveable pulley
Torque and work is a product of force and distance.Yet torque and work are different.What is it about the distances that makes the torque and work different?
Torque describes a rotational force, caused by a force acting at right-angles to the radius of rotation. To measure torque, we multiply the force, in newtons, by the radius of rotation in metres -so, torque is measured in newton metres (N.m).Work is measured by multiplying the force on an object by the distance through which it moves, and is measured in joules (J).The work done by force of torque (not by torque) is determined by multiplying the force, not by the radius of rotation, but by the distance the force acts around the circumference of rotation. So, if torque causes a complete rotation, then the work done by that torque will be the force times (2 pi r).One joule is equal to one newton-meter. It is a measure of work or energy.Torque can be expressed in joules (J), but they really mean joules per radian. They're talking about the amount of work this torque is capable of doing for each radian of rotation. When using radian measure mention of radian is often left out, as in this case.
In what simple machine is neither force nor distance is multipled?
A simple pulley can be used just to alter the direction of the force without multiplying it (although compound pulleys can also be used to multiply force).
Are simple machines unable to multiply the applied effort force?
no
A machine is used to multiply?
Machines multiply themselves, creating a machine army to take over the world.
If the machine cannot multiply the amount of work what is the advantage of using a machine?
A machine decreases the amount of force needed to work, as it distributes the force throughout a larger distance.
How is work done by a force measures?
That is usually calculated, by multiplying the force by the distance.
What is the force exerted by machines?
torque
What is another word for fulcrum?
The fulcrum is the support about which a lever pivots.The fulcrum is the pivot point in a lever (or other simple machines ) to either multiply the mechanical force (effort) that can be applied to another object or resistance force (load), or multiply the distance and speed at which the opposite end of the rigid object travels. =]
What is force times distance?
Torque is calculated by multiplying a force by the distance from the fulcrum at which it acts.
What would life be without simple machines?
Do you mean technological development? Then the answer is no. All complex machines are made up of simple machines in various combinations. Without the one, you can't have the other. The world would go on, of course, but the technological complexities of its modern civilizations could not exist without simple machines.
When dealing with simple machines and compound machines how do you find the force?
you can measure
Why do machines the less force to do the same amount of work?
Because machines allow force to be applied over a greater distance.
If your triple the amount of mass what happens to the force?
Assuming that nothing else changes, multiplying the mass x3 will result in multiplying the force x3. F = m*a --> (3m)*a = 3F
