Which of the following part of the spring is attached to the sleeve?
Porter governor is used to vary the speed of the turntable in a gramophone.
In case of pickering governor, the central load is_______
From the data given:Dimensions of spring = 6mm wide, 0.12 mm thick and length = 48 mmmass attached to each leaf at centre = 25gDistance between spindle axis and C.O.M when the governor is at rest = 8mmSleeve lift = 0.6mmE= 200 GN/mm2Find the speed of the turntable in rpm if ratio of the governor speed to the turntable speed is 10.
From the following data calculate the speed of governor in rpm.Dimensions of spring = 6mm wide, 0.12 mm thick and length = 48 mmmass attached to each leaf at centre = 25gDistance between spindle axis and C.O.M when the governor is at rest = 8mmSleeve lift = 0.6mmE = 200 GN/mm2
A Pickering governor is driving a gramophone. Each disc attached to the centre of a leaf spring has a mass of 20 g. The width of each spring is 5 mm and thickness of 0.125 mm. The effective length of each spring is 40 mm. The distance from the spindle axis to the centre of gravity of the mass when the governor is at rest, is 10 mm, find the speed of the turntable in rpm if ratio of the governor speed to the turntable speed is 10.5.

The effective length of each spring is 40 mm. The distance from the spindle axis to the centre of gravity of the mass when the governor is at rest, is 10 mm. Find the speed of the governor in rpm when the sleeve has risen to a height of 0.8 mm. (E = 210kN/mm2)
The weights move inwards and the springs bend as they rotate about the spindle axis with increasing speed.
