QUESTION: 1

A porter governor has a maximum and minimum speeds of 250 rpm and 200 rpm respectively. If the effective load on the sleeve is 400 N, the governor effort would be

Solution:

The effort of governor is the mean force exerted at the sleeve for a given percentage change in speed

QUESTION: 2

For a Hartnell governor, the loads on the spring at the lowest and highest equilibrium speeds are 200 N and 50 N respectively, If the height of governor is 1.5 cm, the stiffness of spring would be

Solution:


∴ K = 76.67 kN/m

QUESTION: 3

A governor is said to be
1. sensitive when it readily responds to small change in speed
2. isochronous if it has no sensitivity
3. hunting if it is too sensitive
which of these statements is/are true?

Solution:
QUESTION: 4

A Hartnell governor is a governor of the

Solution:

Classification of Governors

QUESTION: 5

Which one of the following governor widely used in Gramophone

Solution:
QUESTION: 6

Sensitiveness of the governor is defined as the ratio of the

Solution:

Sensitiveness is defined as the ratio of the difference between the maximum and minimum equilibrium speeds to the mean equilibrium speed.

QUESTION: 7

Sensitivity of an isochronous governor is
Hence sensitivity = ∝

Solution:


For isochronous governor range of speed = 0.
Hence sensitivity = ∝

QUESTION: 8

For spring controlled governors the controlling force curve would be

Solution:

For spring controlled governor

QUESTION: 9

For a spring controlled governor to be stable the controlling force (f) is related to the radius (r) by the equation

Solution:

QUESTION: 10

Which of the following governor can not be isochronous governor

Solution:

Spring controlled governor can only be isochronous. Since watt governor is not spring controlled governor hence it can not be isochronous.
