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

Yes, it will solve the problem of energy crisis and conserve biodiversity the reason is the majority of energy is wasted in the form of heat energy due to friction. In order to develop more electrical energy, we are depending on coal, petroleum, gas, nuclear energy, and hydroelectricity. The production of energy from these sources except hydroelectric power causes severe air pollution which is affecting animals and plants. So energy should be conserved by means of reducing friction.
