Problem 43E
The flywheel of a gasoline engine is required to give up 500 J of kinetic energy while its angular velocity decreases from 650 rev/min to 520 rev/min. What moment of inertia is required?
ANSWER:
Solution 43E
Step 1 of 4:
In the given problem, we need to calculate the moment of inertia(I) required to change the Kinetic energy of the skywheel by =500 J by reducing the angular speed from
= 650 rev/min to
= 500 rev/min.
Given data,
Change in kinetic energy, =500 J
Initial angular speed, = 650 rev/min
Final speed, = 500 rev/min
To find,
Initial kinetic energy, =?
Final kinetic energy, =?
Moment of inertia, I=?
