Q3 A Hartnell governor having a central sleeve spring and two right-angled

bell crank levers moves between 290 r.p.m. and 310 r.p.m. for a sleeve lift

of 15 mm. The sleeve arms and the ball arms are 80 mm and 120 mm

respectively. The levers are pivoted at 120 mm from the governor axis and

mass of each ball is 2.5 kg. The ball arms are parallel to the governor axis

at the lowest equilibrium speed. Determine: 1. loads on the spring at the

lowest and the highest equilibrium speeds, and 2. stiffness of the spring.

bell crank lever are 120 mm and 100 mm respectively and if the distance

between the centre of pivot of bell crank lever and axis of governor spindle

is 140 mm, determine the initial compression of the spring taking into

account the obliquity of arms.If friction is equivalent to a force of 30 N at

the sleeve, find the total alteration in speed beforethe sleeve begins to

move from mid-position.
