Question

When the speed of the governor increases, which of the following effect does friction causes?

(a) Prevents downward movement of sleeve

(b) Prevents downward movement of sleeve

(c) Prevents radial inward movement of balls

(d) Increases upward movement of sleeve

I had been asked this question in quiz.

This interesting question is from Coefficient of Insensitiveness in chapter Governors of Machine Dynamics

Answer 1

Correct choice is (b) Prevents downward movement of sleeve

To explain I would say: In actual conditions there is always friction acting at joints and operating mechanisms of the governor, as a consequence when the speed of rotation increases.
