Test: Governors - 2 - 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?

Test: Governors - 2 - Question 4

A Hartnell governor is a governor of the

Detailed Solution for Test: Governors - 2 - Question 4

Classification of Governors

Test: Governors - 2 - Question 5

Which one of the following governor widely used in Gramophone

Test: Governors - 2 - Question 6

Sensitiveness of the governor is defined as the ratio of the

Detailed Solution for Test: Governors - 2 - Question 6

 The sensitiveness is defined as the ratio of the difference between the maximum and minimum equilibrium speeds to the mean equilibrium speed. A governor is said to be isochronous when range of speed is zero for all radii of rotation of the balls within the working range, neglecting friction.

Test: Governors - 2 - Question 7

Sensitivity of an isochronous governor is
Hence sensitivity = ∝

Detailed Solution for Test: Governors - 2 - Question 7


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

Test: Governors - 2 - Question 8

For spring controlled governors the controlling force curve would be

Detailed Solution for Test: Governors - 2 - Question 8

For spring controlled governor

Test: Governors - 2 - Question 9

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

Detailed Solution for Test: Governors - 2 - Question 9

Test: Governors - 2 - Question 10

Which of the following governor can not be isochronous governor

Detailed Solution for Test: Governors - 2 - Question 10

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