At about 1:32 the statement of Archimedes Principle needs to have qualification, as stated it is only true IF THE OBJECT FLOATS it displaced its weight of water, iron objects clearly do not displace their weight in water, therefor they sink. This is brought out later, but is confusing at first. Otherwise good video!
Arthur Mercer didn't Archimedes develop his theory in order to test if a crown was pure gold? The water taken up by the solid object that sinks is displaced to another location, so his definition is correct.
The above example doesn't consider internal inflation pressure. I'm keen to know how the buoyancy of an inflatable pontoon with a 140l capacity will be affected by inflation pressure, i.e. how will the carrying capacity decrease if the pressure drops from 7 psi to 5 psi.
More pressure means more molecules of air which means more weight. If the toon doesn't increase in size at all from the inflation it will just be heavier and sink more.
@@mattfuchs7626 based on experience with Chiliboat water bikes, I can now confirm the following: more pressure = more carrying capacity. Low pressure = passenger will sink.
How buoyancy works not how it is caculated...
The Archimedes principal is the submerged object displace equal amount of volume of water.
I think you guys can deduce the math from the explanation, for my part this video was very helpful thank you!
Thanks. Very helpful.

M..ur new subscriber😍
depends on the type of wood also ;)
thank you
Nice vid thanks
terrible video. no help at all. misleading title.
yeah so much bullshit i never heard in my life.
I understand it
Yeah I agree terrible. Will have to try a different video
Why do you have to be so mean :(
