It is equal to the ratio of the load divided by the distance of the fulcrum.
MA of inclined plane:Distance moved parallel to slope / vertical distance moved:Reciprocal of sin of incline angle (from horizontal):1 / ( sin ( incline angle ) )
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).
Lever: A lever consists of a rigid bar (the lever arm) that pivots around a fixed point called the fulcrum. By applying a force at one end of the lever, you can lift or move a load at the other end. Depending on the positions of the force and load relative to the fulcrum, levers can amplify force or distance. Pulley: A pulley is a wheel with a groove that holds a rope, cable, or belt. When you pull on one end of the rope, it moves the load attached to the other end. Fixed and movable pulleys can change the direction of force or provide a mechanical advantage, making it easier to lift heavy objects. Wheel and Axle: A wheel and axle consist of a larger wheel connected to a smaller axle. When force is applied to the wheel, it generates rotational motion that can be used to move loads. The mechanical advantage depends on the ratio of the wheel's radius to the axle's radius. Inclined Plane: An inclined plane is a flat surface that is sloped. By sliding an object along the inclined plane, you can exert a smaller force over a longer distance to move the object to a higher or lower elevation. This reduces the force required to lift the object vertically. Wedge: A wedge is a double-inclined plane used to split or separate objects. When you apply force to the thick end of the wedge, it generates a large force at the thin end, making it useful for cutting, splitting, or prying. Screw: A screw is an inclined plane wrapped around a cylindrical shaft. When you rotate the screw, it moves along its threads and can lift or hold objects. Screws provide both a mechanical advantage and a way to generate motion over a distance.
A wedge and a lever.
Simple machines are basic devices or mechanical powers on which other machines are based (eg, lever, wedge, pulley, wheel and axle, inclined plane, screw).
the formula for the mechanical advantage of an inclined plane is the length divide by the height.
MA of inclined plane:Distance moved parallel to slope / vertical distance moved:Reciprocal of sin of incline angle (from horizontal):1 / ( sin ( incline angle ) )
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.
Ideal Mechanical Advantage for an Inclined Plane is equal to the length of the incline divided by the height of the incline.
Long gently slope inclined plane
Mechanical Advantage
The slope of an inclined plane is found by dividing the rise of the plane by the run of the plane. also the ideal mechanical advantage.
The ideal mechanical advantage of an inclined plane is a ratio describing the length one has to travel to raise a load by a desired height. To obtain this ratio, divide the length of the plane's sloped face by the height of the inclined plane. IMA = Slope length / height
ignoring friction or ideal mechanical advantage
The forces are divided into a horizontal and a vertical component, so that you do not have to lift the weight in full directly. The disadvantage is that you get more friction, so that part of the advantage is negated.
The mechanical advantage of an inclined plane is equal to length divided by height (l/h). Therefore, if the length is less than than the height, the mechanical advantage would be less than one.
Lesser the height of inclined plane, and more the length of it, More will be the mechanical advantage of inclined plane i.e less effort would be applied.
