## Theory of Machine Which of the following governor is used to drive a gramophone?

Hartnell governor
Watt governor
Pickering governor
Porter governor

## Theory of Machine Cam angle is defined as the angle

Through which, the cam rotates during the period in which the follower remains in the highest position
During which the follower returns to its initial position
Of rotation of the cam for a definite displacement of the follower
Moved by the cam from the instant the follower begins to rise, till it reaches its highest position

## Theory of Machine The maximum or minimum value of the swaying couple is

± 2a (1 - c) m.ω².r
± a (1 - c) m.ω².r
± c.m.ω².r
± (a/√2) (1 - c) m.ω².r

Crank has uniform angular velocity
Crank has uniform angular acceleration
Crank has nonuniform angular acceleration

## Theory of Machine The frictional torque transmitted in a truncated conical pivot bearing, considering uniform pressure, is
