How can the mechanical advantage of a lever be increased?
A) by applying a larger force
B) by making the lever shorter
C) by applying the force farther from the fulcrum
D) by moving the fulcrum away from the load
The mechanical advantage of a machine is the factor by which it multiplies any applied force. It is a measure of the ratio of output force to input force.
Mechanical advantage of levers depends on how far away each are from the fulcrum.
The mechanical advantage of a lever is increased when either the effort is moved further away from the fulcrum or the load is shifted closer to the fulcrum, or both.
