In case of flywheel, the maximum fluctuation of energy is the

Detailed Solution: Question 3

Maximum fluctuation of energy

Test: Flywheels - 2 - Question 4
Save

The maximum fluctuation of energy during a cycle for a flywheel is

Detailed Solution: Question 4



Test: Flywheels - 2 - Question 5
Save

The amount of energy absorbed by a flywheel is determined from the

Detailed Solution: Question 5

The amount of energy absorbed by a flywheel is determined form the torque-crank angle diagram. The area under torque-crank angle diagram is known as turning moment.

Test: Flywheels - 2 - Question 6

Why is the mass of flywheel concentrated in the rim?

Detailed Solution: Question 6

Flywheel stores energy in the form of inertia and its interia will be more for heavy mass at its periphery. This is the reason mass of flywheel is concentrated in the rim.

Test: Flywheels - 2 - Question 7
Save

The safe rim velocity of a flywheel is influenced by the

Detailed Solution: Question 7

Rim velocity 
where
σ = centrifugal stress of circumferential stress
ρ = density of rim materia!
Hence, rim velocity is the function of centrifugal stress and density of rim material.

Test: Flywheels - 2 - Question 8
Save

The crank-effort diagram of an engine running a machine is showing the areas above and below the mean line (in joules). What is the maximum fluctuation of energy in the below diagram?

Detailed Solution: Question 8



Maximum energy = E + 50 
Minimum energy = E
Maximum fluctuation of energy
= E + 50 - E = 50J

Test: Flywheels - 2 - Question 9
Save

For a certain engine having an average speed of 1200 rpm, a flywheel approximated as a solid disc, is required for keeping the fluctuation of speed within 2% about the average speed. The fluctuation of kinetic energy per cycle is found to be 2 kJ. What is the least possible mass of the flywheel if its diameter is not to exceed 1 m?

Detailed Solution: Question 9

Average speed

we know that

Test: Flywheels - 2 - Question 10
Save

Which of the following statement is correct?

Detailed Solution: Question 10

Flywheel is used to control the variations in speed during each cycle of an engine. While the function of a governor is to maintain the speed of an engine within specified limit whenever, there is a variation of load.
