Question

new techniques being adopted to reduce energy losses due to friction pictures​

Answer 1

Answer:

Friction is to blame for energy waste since it causes various components of a machine, such as a drip irrigation motor, to wear out owing to excessive heat generated, which lowers a machine's performance.

Explanation:

Humans are using a variety of new methods to lessen energy losses through friction, including:

• Devices that can convert sliding friction into a much smaller sort of rolling friction include wheels, ball bearings, roller bearings, air cushioning, and other fluid bearings.
• Low friction bearings frequently make use of a wide range of thermoplastic materials, including nylon, HDPE, and PTFE.
• Lubricants: Placing a lubricant among two surfaces, such as oil, water, or grease, reduces friction by often significantly lowering the coefficient of friction.
• A recently found phenomenon called superlubricity, which is the significant reduction of friction between two sliding objects to nearly zero values, has been reported in graphite. There would still be a very little amount of frictional energy lost. Acoustic lubrication makes noise as a lubricant rather than constantly using thin, turbulent fluids or powdered materials like graphene and talc to reduce friction.
• By adding a micro-scale vibration to one of the pieces, you can also decrease friction between two moving parts. This can be dither, which is vibration noise, or sinusoidal vibration like that utilised in ultrasonic cutting.

Answer 2

Explanation:

Friction is a force that opposes the motion of bodies.

Work done to overcome the friction results in heat energy, that gets dissipated, and may even cause wear and tear.

To reduce the energy losses due to friction, many techniques have been adopted:

1. Using lubricants such as oil, water or grease placed between two surfaces in contact.
2. Use of wheels, ball bearings and fluid bearings that change sliding friction into a rolling friction.
3. Use of thermoplastic materials such as nylon, HDPE,  PTFE and etc.
4. Use of superlubricity, the sliding regime where the friction almost vanishes.
