Question
Suggest ways in which friction can be minimized.
Answer
1. Ball bearings: Ball bearings consist of small metal balls held in a raceway, which reduces friction by allowing smooth rolling motion.
2. Lubrication: Lubrication involves the application of a lubricant, such as oil, grease, or a specialized lubricating fluid, between the two surfaces in contact.
3. Rollers 4. Surface modification: Surface modification techniques, such as polishing or smoothing the surfaces, aim to alter the surface properties of materials to reduce friction.
