What is an Inclined Plane?
An inclined plane; plural noun: inclined planes, a plane inclined at an angle to the horizontal. A sloping ramp up which heavy loads can be raised by ropes or chains.
An inclined plane is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load. The inclined plane is one of the six classical simple machines defined by Renaissance scientists.
Real life examples of an Inclined Plane
- Wheel chair ramp
- Airplane emergency evacuation slide
- Delivery ramp
How it provides a mechanical advantage
The mechanical advantage MA of a simple machine is defined as the ratio of the output force exerted on the load to the input force applied. For the inclined plane the output load force is just the gravitational force of the load object on the plane, its weight Fw. The input force is the force Fi exerted on the object, parallel to the plane, to move it up the plane. The mechanical advantage is The MA of an ideal inclined plane without friction is sometimes called ideal mechanical advantage (IMA) while the MA when friction is included is called the actual mechanical advantage (AMA).
