1.	In the formula l1=1.75dc, what is dc?(a) Diameter of bore(b) The diameter of the connecting rod(c) The diameter of crankpin(d) Diameter of pistonThe question was posed to me in an internship interview.Origin of the question is IC Engine in division Design of IC Engine Components of Automotive Engine Design
Answer» Right choice is (C) The diameter of CRANKPIN For explanation I would say: In the formula l1=1.75dc, l1 is the length of the crankpin and dc is the diameter of the crankpin, generally d is ALWAYS used to REPRESENT diameter.
