 | | In physics and engineering, mechanical advantage (MA) is the factor by which a mechanism multiplies the force put into it. |
 | | Typically this is a fairly large difference, leading to a proportionately large mechanical advantage. |
 | | This allows even simple wheels with wooden axles running in wooden blocks to still turn freely, because their friction is overwhelmed by the rotational force of the wheel multiplied by the mechanical advantage. |
