1.	As the engine speed increases, which force acts against the spring tension?(a) Rolling force(b) Friction force(c) Centrifugal force(d) Both rolling and friction forceThe question was posed to me during an online interview.This interesting question is from Diesel Engine Fuel Supply System in portion Diesel Engine Fuel Supply System of Automotive Engine Design
Answer» The correct option is (c) Centrifugal FORCE Explanation: As the engine speed increases, the centrifugal force DUE to WEIGHTS acts against the spring tension. Once the FORMER exceeds the latter, the weights FLY apart, causing the other ends of the bell crank levers to raise the sleeve.
