== Actual mechanical advantage is the number of times force exerted on a machine is multiplied by the machine. Ideal force is just a theory. The formula for mechanical advantage is mechanical advantage== out put force divided by input force.The formula for efficiency is efficiency=output work divided by input work times 100%. Output force is the force exerted on the machine. Input force is the force you exert on the machine. ===
