## Theory of Machine The height of a Watt's governor is

Inversely proportional to speed
Directly proportional to (speed)²
Inversely proportional to (speed)²
Directly proportional to speed

## Theory of Machine In multi V-belt transmission, if one of the belt is broken, we have to change the

Broken belt
There is no need of changing any one as remaining belts can take care of transmission of load
All the belts
Broken belt and its adjacent belts

## Theory of Machine A spring controlled governor is found unstable. It can be made stable by

Increasing the spring stiffness
Increasing the ball mass
Decreasing the ball mass
Decreasing the spring stiffness

## Theory of Machine A governor is said to be stable, if the

Radius of rotation of balls increases as the equilibrium speed decreases
Radius of rotation of balls decreases as the equilibrium speed decreases
Radius of rotation of balls increases as the equilibrium speed increases
Radius of rotation of balls decreases as the equilibrium speed increases

## Theory of Machine In a hydrodynamic journal bearing, there is

A thick film of lubricant between the journal and the bearing
A forced lubricant between the journal and the bearing
A very thin film of lubricant between the journal and the bearing such that there is contact between the journal and the bearing
No lubricant between the journal and the bearing
