Given that a lever has a mechanical advantage of 6.0 and is 100% efficient, if the resistance is to be lifted 2.0 inches, then how far must the effort move? De = _____ in.
The mechanical advantage of a machine is the ratio of the force produced by the machine to the force applied to it. Therefore, we may calculate the applied force using: Mechanical advantage = force by machine / force applied 6 = 2 / force applied Force applied = 1/3
Thus, the distance that the effort must move will be 1/3 inch
