Pass Ratio : 100%
The sensitiveness of the governor ____________ as the speed range decreases.
remains unaffected
decreases
increases
none of the mentioned
Explanation:
For a given lift of the sleeve, the sensitiveness of the governor increases as the speed range decreases.
Question 4

Pass Ratio : 100%
Which of the following governor is used to drive a gramophone?
Watt’s governor
Porter governor
Pickering governor
Hartnell governor
Explanation:
A Pickering governor is mostly used for driving gramophone. It consists of three straight leaf springs arranged at equal angular intervals round the spindle. Each spring carries a weight at the centre.
Question 5

Which of the following is a spring controlled governor?
Hartnell governor
Hartung governor
Wilson-Hartnell governor
All of the mentioned
Explanation:
None
Question 6
Marks : +2 | -2
Pass Ratio : 100%
The sensitiveness of a governor depends upon the lift of the sleeve.
True
False
Explanation:
In general, the greater the lift of the sleeve corresponding to a given fractional change in speed, the greater is the sensitiveness of the governor.
Question 7

A pendulum type governor is a Watt governor.
True
False
Explanation:
A Hartnell governor is a spring loaded governor.
Question 8

In a Hartnell governor, the stiffness of the spring is given by
S1 + S2/h
S2 – S1/h
S1 + S2/2h
S1 – S2/2h
Explanation:
h = (r1 – r2y/x
Question 9
Marks : +2 | -2
Pass Ratio : 100%
For two governors A and B, the lift of sleeve of governor A is more than that of governor B, for a given fractional change in speed. It indicates that
governor A is more sensitive than governor B
governor B is more sensitive than governor A
both governors A and B are equally sensitive
none of the mentioned
Explanation:
In general, the greater the lift of the sleeve corresponding to a given fractional change in speed, the greater is the sensitiveness of the governor.

dead weight governor
pendulum type governor
spring loaded governor
inertia governor
Explanation:
A Hartnell governor is a spring loaded governor.
