CBSE Class 11-science Answered
Explain why, the lubricant oils used in our automobiles should be of high viscosity?
Asked by Topperlearning User | 01 Aug, 2014, 11:16: AM
Expert Answer
When oil is used as a lubricant in machines, it forms a thin layer over the metallic parts of the machinery. Hence, during normal working of the machinery, the metallic parts do not come in direct contact with each other. Now, for the oil layer to be effective as a lubricant for a long time, the oil should be of high viscosity.
