Mechanical Advantage lets you use a small amount of force to lift a heavy weight. You can not pick up the corner of a car to change the tire. You can use a jack. Mechanical advantage lets you move your arm down several feet to move the jack up a fraction of an inch. By moving your arms many times, you can lift a heavy car. You can change your tire and not be stuck off in the woods, and have to walk several miles to get someone to help you. I think that is important.
Mechanical advantage is maximum when weight lifted is extremly high and for which C/W is extremely small so as to be negleted, Max. Mechanical Advantage=1/m
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.

The mechanical Advantage is FORCE TIMES DISTANCE
The actual mechanical advantage is usually less, due to losses.
Mechanical Advantage;The ratio of load and effort is called mechanical advantage of any machine.Mathematical Formula Of Mechanical AdvantageMechanical Advantage = Load / EffortUnit Of Mechanical AdvantageAs mechanical advantage is the ratio of two forces, therefore it has no unit.
The mechanical advantage is when the fulcrum is closer to the effort and creates a advantage
Mechanical advantage the resistance force. Mechanical advantage is equal output force divided by input force.
Mechanical advantage equals resistance force.
In a mechanical advantage system, the force is multiplied by the factor of the mechanical advantage. The formula for mechanical advantage is MA = output force / input force. This means the force can be multiplied by the mechanical advantage value.
Mechanical Advantage: F(out)/ F(in) Actual Mechanical Advantage is the ratio of Force outputed to Force inputed. (AMA=Fo/Fi) Similarly, IMA (Ideal Mechanical Advantage) = di/do
775 is a number, not a machine. It, therefore, has no mechanical advantage.
Mechanical Advantage = Effort/Load
Mechanical advantage=load/effort
it is less than the ideal mechanical advantage
