SUMMARY

The discussion focuses on calculating the mass of a rim-type flywheel with a mean radius of 75mm and a torque of 100Nmm. The flywheel accelerates from rest to a speed of 600 RPM while traveling a distance equivalent to 1000 revolutions. Participants emphasize the importance of understanding angular momentum and suggest listing relevant equations to solve the problem accurately. The correct application of these equations will lead to the determination of the flywheel's mass.

PREREQUISITES
  • Understanding of angular momentum principles
  • Familiarity with rotational dynamics equations
  • Basic knowledge of torque calculations
  • Ability to convert RPM to linear distance
NEXT STEPS
  • Study the equations related to angular momentum and rotational motion
  • Learn how to calculate mass using torque and angular acceleration
  • Research the conversion of RPM to linear distance for circular motion
  • Explore examples of flywheel dynamics in engineering applications
USEFUL FOR

Mechanical engineers, physics students, and anyone involved in the design and analysis of flywheel systems will benefit from this discussion.

1.Determine the mass of a rim type flywheel who’s mean radius is 75mm. If it travels a distance of 1000 revolutions when a torque of 100Nmm is applied. To travel this distance the fly wheel accelerates from rest to a speed of 600RPM.


I have no idea where to start on this one! Please could anyone advise?
Thanks,

You sure you transcribed the question right? The phrasing and terminology seem a little screwy. Traveling a distance? Where? How?

Anyhow, you probably need to start looking at angular momentum. There is your start.
 
HNCMATHS: Start by finding and listing relevant equations, such as here[/color], here[/color], and here[/color]; and start plugging in the given parameters. List relevant equations, and show your work. And then someone might check your math. Hint 1: Note that rg = r.
