TO FIND THE DOWNWARD FORCE ALONG AN INCLINED PLANE, ACTING ON A ROLLER DUE TO GRAVITATIONAL PULL OF EARTH AND STUDY ITS RELATIONSHIP WITH THE ANGLE OF INCLINATION (THEETA) BY PLOTING A GRAPH BETWEEN FORCE AND SIN THEETA.
OPERATING MANUAL The inclined plane consists of a smooth plane hinged to a base so that it can be set at any desired angle. Consider a heavy metal roller connected to a scale pan by a light extensible string passing over a frictionless pulley resting on a plane. when a body of mass(m) is placed over an inclined plane, that is inclined at an angle with the horizontal, its weight mg acts vertically downward. The component mg cos(theeta) of the weight acts normally downward on the plane balances the upward normal reaction (say R) of the inclined plane. The component mg sin(theeta) of the weight acting parallel to the inclined plane downwards, produces motion of the body.
