## Theory of Machine If the radius of gyration of a compound pendulum about an axis through e.g. is more, then its frequency of oscillation will be

More
Less
Same
Data are insufficient to determine same

## Theory of Machine In gramophones for adjusting the speed of the turntable, the following type of governor is commonly employed

Inertia governor
Wilson Hartnell governor
Hartung governor
Pickering governor

## Theory of Machine A spring controlled governor is said to be isochronous when the controlling force

Decreases as the radius of rotation increases
Increases as the radius of rotation increases
Remain constant for all radii of rotation
Increases as the radius of rotation decreases

## Theory of Machine A spring controlled governor is said to be unstable when the controlling force

Decreases as the radius of rotation increases
Increases as the radius of rotation increases
Remains constant for all radii of rotation
Increases as the radius of rotation decreases
