Explain any 3 methods of reducing friction

WebNov 16, 2024 · INTRODUCTION. Since friction and wear are responsible for about a quarter of the total energy losses worldwide ( 1 ), new methods of minimizing these untoward effects could be of immense value for the energy-efficient economy of the future. One source of friction is the so-called contact electrification (also known as … WebJun 6, 2024 · Another method of reducing friction is by using bearings. When ball bearings are introduced between two surfaces friction is reduced because of the freely rotating metal balls. To increase friction, the surfaces in contact have to be made rough.
