Question 13

Q13) Give a reason why oiling or greasing is done on the exposed moving iron parts of machinery and not preferred on heavy stationary iron parts.

Solution :

Oil or grease on the exposed moving iron parts of machinery forms a coating which protects it from rusting. It reduces friction in the machinery. Oiling or greasing is not preferred on heavy stationary iron parts as red lead oxide paint is used on these parts.
