Friction on Inclined Plane Calculator. An inclined plane is also known as a ramp. It is a flat supporting surface tilted at an angle, with one end higher than the other. It is one of the six classical simple machines defined by Renaissance scientists. When an object slide down to an inclined plane, friction is involved and the force of friction. You can use an object on an incline to determine the static coefficient of friction by finding the angle at which the force of gravity overcomes the static friction. Perpendicular force reduced When an object is placed on an incline, the force perpendicular between the surfaces is reduced, according to the angle of the incline That is the angle where the force of gravity is strong enough to overcome the static sliding friction. By simply knowing the angle or the inclination, you can then calculate the static sliding coefficient of friction between the two materials. You can cover the ramp with various materials to determine different coefficients If the coefficient of static friction is 0.4, calculate the angle at which the box begins to slide down the plank as it tilts.
