Spherical pendulum filled with water

Click For Summary
SUMMARY

A spherical pendulum filled with water can be treated similarly to one made of ice, provided that the sphere is completely filled. This ensures that the pendulum acts as a rigid body, maintaining a constant center of mass during motion. The discussion emphasizes the importance of the pendulum's fill state to achieve this behavior.

PREREQUISITES
  • Understanding of rigid body dynamics
  • Basic principles of pendulum motion
  • Knowledge of fluid mechanics
  • Familiarity with spherical geometry
NEXT STEPS
  • Research the dynamics of rigid body motion in pendulums
  • Explore fluid dynamics principles related to motion
  • Study the effects of mass distribution in pendulum systems
  • Investigate the mathematical modeling of spherical pendulums
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in the dynamics of pendulum systems and fluid mechanics.

Can a spherical pendulum filled with water be treated in the same as one made of ice?

I think yes. But the condition is sphere must be fully filled. So that it acts as a rigid body and its center of mass doesn't change.
