Question: Generally the mass of fly wheel is concentrated in its rim. Why?...
Generally the mass of fly wheel is concentrated in its rim. Why?
A
To obtain a strong wheel
B
To obtain stable equilibrium
C
To increase the moment of inertia
D
To decrease the moment of inertia
Answer
To increase the moment of inertia
Explanation
Solution
In flywheel mass is concentrated at the rim to increase the moment of inertia of the flywheel. Thus, if there is some change in rotational kinetic energy, the change in angular velocity is small. This helps in maintaining uniform motion of the flywheel.
