The angle described by the shaft in radians in one second for a flywheel rotating at a constant speed of 3000 rpm is:
Answer: 30 𝜋
Explanation
To find the angle in radians per second, first convert the rpm (revolutions per minute) to radians per second.
3000 rpm = 3000/60 revolutions per second = 50 revolutions per second.
Each revolution is 2π radians.
So,
50×2π=100π radians per second.
