In the distance from the fulcrum to the input forcedivided by the distance from the fulcrum to theoutput force.

Exactly the same. The reduction in gravitational force has no effect on M.A., which is a matter of simple geometry.

Yes, the simple machine is a lever if you look at the top of a normal playground swing.

The answer is mechanical advantage, not efficiency!

To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).

The "Ideal Mechanical Advantage" of a simple machine isIMA = output force /input force . To find the 'actual' or real-world mechanical advantage,multiply the IMA by the machine's efficiency.

it means the mechanical advantage is greater.

80 Is the Output force

Whatever output force is required, you can divide it by the "mechanical advantage" to calculate the input force.
