1.	What is Frictional Power?(a) It is the power loss due to friction(b) It is the power generated by friction(c) It is the power generated by crankshaft bearings(d) It is the friction generated due to powerThe question was posed to me during an online interview.My enquiry is from IC Engine in portion Design of IC Engine Components of Automotive Engine Design
Answer» Correct answer is (a) It is the power LOSS due to FRICTION The BEST explanation: Engine is not 100% efficient, there is a power loss due to friction between the PISTON and the cylinder. Therefore, Frictional Power is the power loss due to friction.
