How Are Fan Blades Inclined Planes?
An Inclined Plane is Inclined Inclined planes are really little more than simple flat objects turned at an angle to become a simple machine. The plane may be turned to any angle as long as it is not a right angle, as a right angle would make the plane nothing more than a plane on a different axis. When the plane is inclined, it allows a motor or other input to produce work with considerably less effort than would be required using direct force, as the incline of the plane overcomes vertical or horizontal resistance by displacing it much like a lever would do. To be considered an inclined plane, a simple machine needs only to be flat, inclined, and useful for producing work with reduced input. Fan Blades Are Inclined By their very nature, fan blades are inclined to an angle of less than 90 degrees. When a fan motor turns the blades, the blades move through the air at an incline; the inclined surface passing through the air pushes the air forward, as the air is scooped up by the leading
