What is the Mechanical Advantage of levers?
The mechanical advantage of the lever is that smaller persons can move heavier objects. The lever can be placed under the object and the person can then push down on the lever.
How do you increase the mechanical advantage of a lever?
The mechanical advantage of a lever can be increased by moving the fulcrum towards the load and away from the power end.
