From analyzing the energy fluctuation equation of a flywheel, which of the following conclusions can one arrive at?
1
The flywheel will be large for low fluctuations in energy.
2
For a high-speed engine also, the flywheel will be larger.
3
For similar fluctuations in energy, the flywheel can be smaller if the system tolerates speed fluctuations.
4
The coefficient for speed fluctuation in a flywheel is not limited purely by physical constraints.
