Answer:
Ma of lever is 1means that the applied effort can lift 1 times heavier load using the machine.
The mechanical advantage of a lever is the ra o of the length of the lever on the applied effort side of the fulcrum to the length of the lever on the load force side of the fulcrum. – crowbars, – scissors, – pliers, – tin snips – and seesaws. Effort moves farther than Load. Always mul plies a force.

Answer:
The ideal mechanical advantage equals the length of the effort arm divided by the length of the resistance arm of a lever. In general, the IMA = the resistance force, Fr, divided by the effort force, Fe. IMA also equals the distance over which the effort is applied, de, divided by the distance the load travels, dr.
