When a body moves with constant velocity then acceleration in the body is zero.  Force is zero. We can say that a force is not required to keep a body in motion with constant velocity.

Load Effort  The number of times a machine multiplies the effort force is mechanical advantage.

We know that, mechanical advantage =
