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

Answer;

C) by applying the force farther from the fulcrum

Explanation; 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.
