Why do you say thst lubricating fluids control friction?

Answer 1

We say that because they do their job by allowing the parts of the machine to move more easily and produce less heat. That's what my teacher said.

Answer 2

Lubricating fluids create a barrier between moving surfaces, reducing direct contact and friction between them. This barrier allows the surfaces to glide smoothly over each other, minimizing wear and heat generation. Overall, lubricating fluids help control friction by promoting the separation and easy movement of components.
