Question

The device that reduces the speed of vehicles due to friction.​

Answer 1

• To Identify ways of reducing friction, we have a tendency to initial need to perceive what's the reason for friction.
• There square measure reasons behind friction:
• Whenever two surfaces are available contact, then the temporary bonds begin forming between them, which resist the movement between the surfaces. Higher the world of contact, the larger the number of bonds, higher the worth of friction force.
• The abnormality/Roughness of the surface, the additional rough the surface is, the upper the friction.
• The Value of friction force is proportional to the conventional contact force. the upper the conventional force, the larger is that the friction
• A bearing works on the principle that rolling friction is a smaller amount than slippy friction. It helps in reducing friction between two surfaces connected and maintaining separation between the bearing races, thereby permitting minimal surface contact between Two surfaces.
• Methods for Reduction friction:
• Make the surfaces a touch electric sander. Rough surfaces turn out additional friction and swish surfaces cut back friction.
• creating the surface extremely swish also will increase the friction, as an oversized range of bonds can type then.
• Lubrication is otherwise to form a surface electric sander. staff could be a slippery substance designed to scale back the friction between surfaces.
• Make the article additional efficient. An efficient form is one that permits air or water to flow around it simply, providing the smallest amount of resistance.
• Reduce the conventional force acting between the surfaces connected. The stronger the conventional force engaged on the surfaces, the upper the friction.
• Reduce the contact between the surfaces, so fewer bonds are fashioned. Spheres square measure the most effective form for reducing friction as a result of little of a spherical object is connected with the opposite surface
