Inclined Plane



Useful for study and demonstration of the concept of motion on an inclined surface and its relation to the friction. A pair of polished wooden boards attached together at each end are hinged at one end to a metal baseboard below it so that the wooden boards can be moved to form an inclined surface. One side of the board has a linear scale graduated every 5cm to measure linear distance along its length, while an adjustable and removable angle measurer or arc scale, attached to the metal baseboard on the same side and graduated 0-45ºx1º measures the angle of inclination. The angle measurer also has linear scale graduated in centimeters to measure the vertical height of inclined surface at a point. A plastic pulley attached to the end of inclined boards supports masses suspended from thread, the other end of thread being connected to the objects moving on inclined surface.


An inclined plane can be defined as any plane surface positioned at an angle with respect to the horizontal plane. Geometrically, it can also be called right-angled triangle in which, the hypotenuse is the inclined plane, the base is the horizontal plane and the perpendicular is the vertical height. For experimental purposes, the inclined plane consists of two plane parallel plates or surfaces hinged together so that they can be rotated about horizontal axis as the horizontal and inclined planes. The inclined plane is smoothened to minimize the effects of friction and is also provided with a pulley system for different motion related experiments.
