Centre of gravity of a submerged body?

Click For Summary
SUMMARY

The discussion centers on the calculation of the center of mass for submerged bodies, highlighting confusion between the center of mass and the center of buoyancy. Participants clarify that the center of mass is independent of whether an object is submerged, while the center of buoyancy relates to the volume of fluid displaced. The distinction is crucial for understanding stability in fluid mechanics, particularly in applications involving submerged objects.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Knowledge of buoyancy and Archimedes' principle
  • Familiarity with center of mass calculations
  • Basic physics concepts related to forces and equilibrium
NEXT STEPS
  • Study the principles of buoyancy and how they affect submerged objects
  • Learn about the calculation of center of mass in various geometries
  • Explore stability analysis for floating and submerged bodies
  • Investigate real-world applications of buoyancy in engineering design
USEFUL FOR

Students of physics, engineers working with fluid dynamics, and anyone involved in designing submerged structures or vessels will benefit from this discussion.

Hi guys,

I can't get my head around the centre of mass of a submerged body at all. the notes I've been given don't actually state how you calculate the centre of mass of the submerged body at all and just state it with no decernable pattern. I did assume that it was the centre of mass of that which is not submerged but that doesn't seem to be the case according to some of the diagrams I've been provided with.

how do i find this point?

Cheers

Why would the center of mass of an object have anything to do with whether or not it is submerged or above ground or in outer space?
 
Perhaps you are thinking of the center of buoyancy, not center of mass?
