Is there a buoyancy force or not?

Click For Summary
The discussion centers around the concept of buoyancy force acting on a cylinder partially submerged in water but fixed to the bottom of a tank. Participants debate whether buoyancy, as described by Archimedes' Principle, applies when the cylinder has no water contact at its base. It is argued that without pressure acting on the bottom, there is no upward buoyant force, while others suggest that even fixed structures like intake towers experience buoyancy forces due to water pressure dynamics. Real-world examples are cited, emphasizing the importance of considering buoyancy in engineering applications, particularly in scenarios where structures are anchored underwater. Ultimately, the conversation highlights the complexities and nuances of buoyancy in practical situations.
