Energy Transfer Between Inertia Wheels

Click For Summary
SUMMARY

The discussion centers on calculating the final RPM of two inertia wheels connected by a clutch, where one wheel is spinning and the other is at rest. The key principle involved is the conservation of angular momentum, which states that the total angular momentum before and after the clutch engagement remains constant. The user has provided specific parameters such as radius, kinetic energy (KE), moment of inertia, and clutch engagement time, but seeks clarity on determining the final torque and RPM. A systematic approach to solving this problem involves applying the conservation of angular momentum formula.

PREREQUISITES
  • Understanding of conservation of angular momentum
  • Knowledge of moment of inertia calculations
  • Familiarity with rotational kinetic energy concepts
  • Basic principles of clutch mechanics
NEXT STEPS
  • Study the conservation of angular momentum in rotational systems

  • Explore the relationship between torque and angular acceleration
  • Investigate examples of clutch engagement in mechanical systems
USEFUL FOR

Mechanical engineers, physics students, and anyone involved in the design or analysis of rotational systems and inertia wheels.

TL;DR
One flywheel is spinning and a 2nd flywheel is at rest. A clutch connects the shafts. What's the final rpm?
Been 20 years since college physics. I have a problem where there are basically two inertia wheels on separate shafts coupled by a clutch. One wheel is spinning and the other is at rest. The clutch engages and connects the shafts. What's the final rpm of both wheels? I'm struggling to find a similar problem to use an example. I know the radius, KE, moment of inertia, rpm, clutch engagement time, etc. but I'm not sure how to determine the final torque because it's not clear how to find the final rpm. If you would please describe the general approach or link a similar problem I'd appreciate it.

If the bearings are good then you can use conservation of angular momentum
