Functions of Lubricating Oil in Machinery

What are the functions of lubricating oil in machinery?

Choose the function that lubricating oil does NOT perform:

a. Cleaning.

b. Powering.

c. Sealing.

d. Cooling.

Answer:

Lubricating oil is used in machinery for cleaning, sealing, and cooling purposes, but it doesn't serve the function of powering the machinery. That's the job of fuel like gasoline or diesel. Therefore, the correct Option is B.

Explanation:

Lubricating oil, often used in engines and machinery, has several important functions that help ensure the efficient and smooth operation of these systems. These functions include cleaning, which involves removing dirt and other impurities; sealing, that means creating a barrier to prevent leakage of gases or fluids; and cooling, where the oil absorbs and dissipates heat generated by the machinery's operation.

However, one function that lubricating oil does not have is powering. The oil doesn't act as a fuel to actually power the machinery or engine. Instead, fuels like gasoline or diesel are typically used for this purpose. So, the answer to your question is b. Powering.
