Determining percentage of work input in lever system

To determine the percentage of work input in a lever system, you need to consider two main factors: the amount of input force applied and the distance over which the force is applied.

1. Calculate the work done by the input force:
Work = Force x Distance
For example, if you apply a force of 100 N over a distance of 2 meters, the work done would be:
Work = 100 N x 2 m = 200 Joules

2. Calculate the total work output of the lever system:
Total Work Output = Output Force x Output Distance
If the output force is 50 N and the output distance is 4 meters, the total work output would be:
Total Work Output = 50 N x 4 m = 200 Joules

3. Calculate the percentage of work input:
Percentage of Work Input = (Work Input / Total Work Output) x 100
In this example, the percentage of work input would be:
Percentage of Work Input = (200 Joules / 200 Joules) x 100 = 100%

Therefore, in this lever system, the input force is responsible for 100% of the work done.
