One of the advantages of the solid lubricants is ___________(a) unstab – InterviewSolution

1.	One of the advantages of the solid lubricants is ___________(a) unstable in radiation(b) high coefficient of friction than liquid lubricants(c) low coefficient of friction(d) permit equipment is simple
Answer» The correct option is (d) permit equipment is simple To explain: The permit equipment is simple so that it can be carried anywhere very easily. Normally, the coefficient of friction of the solid lubricant is low and it is a disadvantage. Another disadvantage is it is unstable in radiation.
