can be either a force advantage or a speed advantage. In the case of oars, the advantage is a speed advantage with the blade moving faster than the handle.
the ratio of the force exerted by a machine to the force applied to it
The advantage created by a machine that enables people to do work while using less force.
(or purchase) A mechanical method of increasing an applied force. Disregarding the effects of friction, if a force of 100 pounds applied to a tackle is magnified to a force of 400 pounds, the purchase or mechanical advantage is said to be four to one, or 4: 1.
The ratio of the output force of a machine to the input force.
Force, multiplied in ability by use of a mechanism, such as a lever, gears, etc.
In physics and engineering, mechanical advantage (MA) is the factor by which a mechanism multiplies the force put into it. Following are simple machines where the mechanical advantage is calculated.
