Question

Given below are two statements:
Statement (I): Flywheels are used to control the fluctuations in speed of machines arising from external sources.
Statement (II): Governors are used to control the fluctuations in speed of machines arising from internal sources.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both Statement I and Statement II are correct
• B. Both Statement I and Statement II are incorrect
• C. Statement I is correct but Statement II is incorrect
• D. Statement I is incorrect but Statement II is correct

Hint:

Governors regulate internal speed fluctuations while flywheels store energy and reduce external fluctuations in rotational speed

Answer 1

The Correct Option is D

Flywheels are used for storing energy to smooth out the fluctuations in a machine’s speed caused by external forces Governors on the other hand control the speed of engines and turbines by adjusting the fuel or air intake to regulate the engine speed due to internal forces
