MA of inclined plane:
Distance moved parallel to slope / vertical distance moved:
Reciprocal of sin of incline angle (from horizontal):
1 / ( sin ( incline angle ) )
MA= the length of the inclined plane/the height of the inclined plane.
It is equal to the ratio of the load divided by the distance of the fulcrum.
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
Those dependent on the vector resolution of forces (inclined plane, wedge, screw) and those in which there is an equilibrium of torques (lever, pulley, wheel).
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.
a big driller lol :P
Ideal Mechanical Advantage for an Inclined Plane is equal to the length of the incline divided by the height of the incline.
( Assuming mass of object on incline plane is in kilograms (kg) ) . Force pulling down incline on object (kilogram force) = object mass * sin (incline angle) . Force of object acting on and normal to incline (kilogram force) = object mass * cos (incline angle) . Mechanical Advantage = 1 / ( sin ( incline angle ) )
The ideal mechanical advantage, or IMA, of an inclined plane is equal to the length of the incline divided by its height. The IMA is calculated without regard to friction.
A single pulley simply changes the direction of the force. A block and tackle or multiple pulleys can offer a mechanical advantage - same as an inclined plane. For the same mechanical advantage, a pulley system may be better because of lower friction.

Allows mechanical advantage, > Output force = Input force * (distance travelled up and parallel to ramp / vertical distance travelled)
no the mechanical advantage does not depends on the mass of the object lifted throgh inclined plane because if we increase the mass then we have to increase the force to pull the object up and the ratio will remain same.
The advantage to using an incline plane (ramp) is that it reduces the amount of work.
the formula for the mechanical advantage of an inclined plane is the length divide by the height.
Since the Mechanical Advantage of the inclined plane is inversely proportional to its height, increasing the height would lower your mechanical advantage and lowering the height would increase it.Alternately, mechanical advantage is directlyproportional to an inclined plane's length, therefore increasing the length would increase your mechanical advantage.
