friction ppt SlideShare
Sometimes friction is not desirable, for example friction between machinery parts, which causes wear and tear. As friction is advantageous to us it is considered as a friend but due to its disadvantages it is a foe. Depending on the circumstance, friction can be a help or a hindrance. Thus it is a necessary evil.

Friction BasicsFriction Basics • Friction is the "evil" of all motion. Friction is a Force that holds back the movement of a sliding object. • Move something left, friction pulls right. Move something up, friction pulls down. 8. Friction BasicsFriction Basics • It appears as if nature has given us friction to stop us from moving anything. 9.

Friction • Friction is the force that hinders or resists the relative motion of the two contacting bodies. • Friction originates from complex molecular and mechanical interactions between the contacting surfaces. • Friction causes wear and generates heat which can lead to premature failure of

17.02.2016· TYPES OF FRICTION There are three main types of friction. They are static friction, sliding friction and rolling friction. a) Static friction is the friction exerted on a object at rest.. b) Sliding friction is the friction exerted when an object slides over a surface.

Influence of temperature on friction of polymeric
The results showed that the friction coefficient of the NBR and UHMWPE/NBR composites exhibited a slight increase with increasing temperature. It was found that the variations in test temperature had less of effect on the friction behavior of the UHMWPE. When the test temperature exceeded 60°C a significant increase in friction and wear of the polymer resin was observed. The experimental

Frictional heat is generated between the wear resistant welding tool and the material of the work pieces. This heat causes the material to soften without reaching the melting point and allows traversing of the tool along the weld line. The maximum temperature reached is of the order of 0.8 of the melting temperature of the material. It leaves a solid phase bond between the two pieces. The

Static vs Kinetic Friction: Why Is Static Friction Greater
However, not all friction is good, as it can also result in wear and tear, such as on the soles of your shoes, the floor-facing surface of your furniture, or the wheels of your car. Today, we are going to look at the two varieties of resistance that apply to dry friction—the force that opposes the movement of two solid objects whose surfaces are in contact.

Contact mechanics Wikipedia
Contact mechanics is the study of the deformation of solids that touch each other at one or more points. A central distinction in contact mechanics is between stresses acting perpendicular to the contacting bodies' surfaces (known as the normal direction) and frictional stresses acting tangentially between the surfaces. This page focuses mainly on the normal direction, i.e. on
Chapter 02: Surface Roughness Analysis and Measurement
The presence of surface films affects friction and wear. The effect of adsorbed films, even a fraction of a monolayer, is significant on the surface interaction. Sometimes, the films wear out in the initial running period and subsequently have no effect. The effect of greasy or soapy film, if present, is more marked; it reduces the severity of surface interaction often by one or more

Maintenance Management SlideShare
Major types of wear include abrasion, friction (adhesion and cohesion), erosion, and corrosion. Wear can be minimized by modifying the surface properties of solids by one or more of "surface engineering" processes (also called surface finishing) or by use of lubricants (for frictional or adhesive wear). 23.

Frictional force with respect to the applied normal load for two different SAMs is shown in Fig 2.Sliding velocity is 0.1mm/sec and sliding distance is 7mm. We can clearly observe that OTS has reduced the frictional force to a very low value when compared to the bare Si and APTMS did not show any reduction; rather, it has shown slightly higher frictional force.
