Respuesta :
I think a lever increases the force by decreasing the distance moved proportionately. Since; work done is given by force multiplied by distance, thus the increase and decrease will cancel out, leaving the same amount of work done. Work done in machines depends on the amount of force applied and the distance, therefore, a change in any of the variables will affect the value of work done.
Work is defined as the product of applied force and distance. If the work done is constant in that condition force is the inverse of the displacement.
What is work?
Work is defined as the product of applied force and the distance through which the body is displaced on which the force is applied.
Work may be zero, positive and negative.it depends on the direction of the body displaced. if the body is displaced in the same direction of the force it will be positive.
while if the displacement is in the opposite direction of the force applied the work will be negative work. if there is no displacement of the body the work done will be zero.
If the work done is constant in that condition force is the inverse of the displacement.
Hence the lever can increase the force by decreasing the amount of displacement or decreasing the length of the lever without changing the amount of work being done.
