Sphere plane contact sliding friction
Did you know?
WebThe Hertzian contact (Hertz 1881, 1882) is referred to the frictionless contact between two bodies. Spherical contact is a special case of the Hertz contact, which is between two spheres, or between a sphere and the surface of a half space. This type of contact is also called the point contact because theoretically the contact spot is a ... WebSince friction always opposes relative motion, the direction of friction is upward along the plane if the object is at rest or sliding down the incline. For example, if the crate you try to push (with a force parallel to the floor) has a mass of 100 kg, then the normal force would be equal to its weight W = m g = ( 100 kg) ( 9.80 m/s 2) = 980 N,

In order to achieve the objectives, a micro optical friction (MOF) apparatus was developed to conduct dry sliding friction experiments and to allow for in situ visualization of the contact area for a sphere … google in pc download freeIf the sphere and plane are idealised as rigid bodies, then contact would occur in just a single point, and the sphere would not move until the tangential force that is applied reaches the maximum friction force. Then it starts sliding over the surface until the applied force is reduced again. Zobraziť viac Contact mechanics is the study of the deformation of solids that touch each other at one or more points.
