I'm trying to understand the 'Lever Principle' and have made up a few questions to help better understand the concept. Although researching the subject I'm having troubles finding any videos or threads containing the idea of fluid being in a hollow tube acting as a see-saw and I'm curious to the idea. The question is if the see-saw or water weight was at an angle if it would act exactly the same as if the see-saw was completely solid aike to a typical lever. I'm also writing up another relevant question regarding the topic that's gets a little bit more into detail.
The photo below has a see saw that's 10 ft in leangth. Each line through it represents 10 lb of water weight so each side of the fulcrum is exactly 50 lb. I understand that its currently at an 80 degree angle and should be equalibrium but please disregard that as I'm just trying to keep it simple for the question.
