QUESTION: 1

### Which one is a correct statement regarding flywheel?

Solution:

A flywheel is used to control the speed variations caused by the fluctuations of energy during each each cycle of operation. It acts as a reservoir of energy which stores energy during the period when the supply of energy is more' than the requirement and releases the energy during the period when the supply of energy is less than the requirements.

QUESTION: 2

Solution:

QUESTION: 3

### The maximum fluctuation of energy in a flywheel is equal to

Solution:
QUESTION: 4

The radius of gyration of a flywheel is 1 m and the fluctuation of speed is not to exceed 1 % of the mean speed of the flywheel. If the mass of the flywheel is 4000 kg and hte engine develops 150 kW at 120 rpm, what is the maximum flucuation of energy?

Solution:

QUESTION: 5

Select the wrong statement;

Solution:

For the same mass of flywheel, the rim type is preferable over disk type flywheels.

QUESTION: 6

Consider the following parameter;-------1
. Limit of peripheral speed
2. Limit of centrifugal stress
3. Coefficient of fluctuation of speed
4. Weight of the rim

Which of these parameters are used in the calculation of the diameter of flywheel rim?

Solution:

σ =  ρv2
σ →  a circumferential stress
ρ→ density o f flywheel material
V→ tangential rim velocity

QUESTION: 7

Which of the following machines does not require a flywheel?

Solution:
QUESTION: 8

If N1 and N2 are the maximum and minimum equilibrium speeds of the flywheel, then maximum fluctuations of energy of flywheel is proportional to

Solution:

QUESTION: 9

A flywheel influences the
