Which of the following is not an advantage of reducing the ring width?

1.	Which of the following is not an advantage of reducing the ring width?(a) Machining the narrow grooves(b) Better resistance to ring scuffing(c) better resistance to ring flutter(d) Ring inertia are reducedThis question was posed to me in final exam.My question is taken from Engine Components topic in section Basic Engine Components of Automotive Engine Design
Answer» The correct choice is (a) MACHINING the narrow grooves For explanation: The advantages of having a REDUCED ring width are better resistance to scuffing, better resistance to ring flutter, problems on ring inertia are reduced, lower PISTON HEIGHT, and CONSEQUENTLY lower engine height and the disadvantage is machining the narrow grooves I’m the piston accurately is quite difficult.
