Question

reducing friction to the lowest possible level in machine tools solves the problem of energy crisis and conserve biodiversity". How do you support the statement? Explain​

Answer 1

Answer:

Reducing frictio

If a device is run by fuel then in case of excess friction, it requires huge amounts of fuel to provide more energy. By lessening the frictional force, it is possible to reduce energy consumption thus paving way for conservation of biodiversity. ( As fuel is obtained from trees and fossils.)
