Answer:

How is the mechanical advantage of a lever calculated?

The mechanical advantage of a lever can be determined by considering the balance of moments or torque, T, about the fulcrum. If the distance traveled is greater, then the output force is lessened. where F1 is the input force to the lever and F2 is the output force.
