One of the tasks of the engineer is to control friction—to increase friction where friction is needed and to reduce it where it is ... by Ron Kurtus. atmosphere. It explains how static electricity is caused by friction between objects and that charged objects are either positively or negatively charged. Found inside – Page 48Lubricant reduces the harmful effects of friction on the tool‐blank interface for the most of metal forming process. Metal flow is sometimes delayed due to residual stress caused by friction and defects in the product. in rolling. As a student, you'll join a national destination for research training! The force acts in the opposite direction to the way an object wants to slide. In this activity, you will study the effects of surface smoothness and the nature of materials in contact on sliding friction. When friction is caused by The transient response of viscosity, following the rapid pressure rise encountered in the contact, is described by a compressional viscoelastic model of the volume response of a liquid to an applied pressure step. Thus friction helps in heating of machine which may damage them Friction Slows down speed of Object Since friction opposes motion,it slows down speed of motion Without friction,vehicles would move faster Friction Reduces Efficiency and Increases Costs Because of friction,more fuel is required to run vehicles like car Additionally, their use is also more prevalent in cases when sandy soils are encountered to greater depths. For one to understand the effect that friction has on an EPP system, it is useful to first consider the ideal response in the absence of friction. friction is useful as well as harmful. we can’t think of a world without friction. we walk, run , and do everything using friction.

Friction drag is the resistance of the air along the surface of the plane. “ Friction, according to its encyclopedia description, is the force that opposes the relative motion or tendency of such motion of two surfaces in contact. be improved. While friction is useful while we walk, write, play, run, etc but it can also be harmful to us like fire accidents, wear, and tear. Friction Introduction to the ways of increasing and decreasing friction: When a body slides over the surface of another body, there is an opposing force acting in opposite direction of motion and this opposing force is called friction.Their are various ways by means of which, we can increase or decrease friction.
