Why is work input equal to the effort force times the effort distance?

That's the definition of "work" ... (force exerted) times (distance through which the force acts).
If you push against the end of a lever with a force 'F' and move it through a distance 'D',
then (F x D) is the work you put into the lever.

What is a Mechanical advantage equal to?
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
How do you calculate the mechanical advantage of a simple machine?
In the distance from the fulcrum to the input forcedivided by the distance from the fulcrum to theoutput force.
Why is the inclined plane helpful?
because it reduces the amount of input force over longer distance
What does input force mean?
input force is force exerted on a machine
Compares the input force with the output force?
Mechanical Advantage which is the output force divided by the input force.
In a second class lever why must you exert input force over a greater distance?
If the input force is applied at a greater distance than the length of the effort arm is increased thereby reducing the effort.
What is the effort force you exert?
input force
What is input distance?
Input Distance is the distance the input force acts through.
How would you describe the effort force?
Effort force is a force used to move an object over distance.Which ball will bounce higher lacrosse ball or tennis ball?Read more: Which_ball_will_bounce_higher_lacrosse_ball_or_tennis_ball
What do you need to know to calculate the mechanical advantage of a compound machine?
torque in * input rpm/output rpm = torque out
What is the definition of output distance?
input distance- the distance the input force acts through
What does input force mean in science?
For a rotational output such as a petrol or diesel engine, the force is Torque, which is measured in Foot.pounds or Newton.meters.
When does output force equal input force?
Output force can only equal input force in a system where there are no losses. In the "real world" we live in, there are losses in every system, and that means that output force can nerver equal input force.
What is the product of the input force through a distance?
force * distance = work
What would be the output force if the input force is 2.5n?
That completely depends on what kind of machinery is between the input and the output. The only thing we can say for sure is that . . . (2.5n) x (the distance it travels) is equal to (output force) x (distance it travels) + (energy lost in the machinery) .
As you increase the effort distance what will happen to the force needed?
When you move a fulcrum as close as you can to the effort force and farthest away from the load, you are pushing on the short end of the lever, so it requires the most effort force to push on the lever and lift up the load. When you move the fulcrum farther away from the effort force and closer to the load, you are pushing on the long end of the lever, so it requires less effort force to lift the load.
What is The force that you exert on a lever called?
The force that you exert on a lever can be called the effort force. The lever has three parts. They are: the fulcrum, the load, and the effort force. This can also be classified as the input force. The force that you exert to perform a task is known as the input force.
