An automobile fitted with a spring loaded Hartnell governor, the flyballs of it rotate at 500 r.p.m. having radius of rotation of 7 cm with sleeve in mid-position and balls arms vertical. The length of ball and sleeve arms is same. The maximum sleeve movement is 2 cm with ±5% variation is speed. The mass of the sleeve is 5 kg and the friction may be assumed to be equivalent of an additional load of 30 N at the sleeve. The effort of governor is sufficient to overcome the friction of the sleeve caused by 1% change of speed at mid-position. Calculate -
- the mass of flyballs
- the spring rate
- the governor effort of 1 % change of speed
- the power of governor
