you worth million subscribers sir. love from India. life saver for exams.

Wow your drawings are great! Looking forward to more of these videos in the fluid mechanics series!

[IGJTHOMAS]

These are amazing, cut the fat out and are straight to it. Looking forward to the example problems to come.

I have watched all mechanics of material, statics, and fluid now i am at solid work thank you for your hard work. I wish there was thermodynamics and heat transfer series.

If a body is submerged inside a liquid, why is it that its weight doesn't participate in the pressure equation?

[Zarthustr]

I have an issue understanding the internal stresses in an object due to buoyancy - if I would put a long steel rod in water -> if it was thin and long enough would it buckle due to buoancy? If I think about this according to the Archimedes principle, it would clearly not, it is just as if the steel rod would have somewhat lower density, but no reason to buckle ... but if I use the piston force principle (where buoyancy is added as an external force B=Crosssection of the rod *p), the answer would be yes, the rod would be under compression at the bottom.
So now one could just say: ok the piston force principle is just wrong ... but then it offers a good explanation of why there is no buoyancy force if e.g. a cylinder sits at the bottom of a water filled beaker (with no water between the lower area of the cylinder and the bottom of the beaker) ... so I can't just throw the piston force principle out of the window ... there is something I do not understand about the internal stresses caused by buoyancy ... can anyone point me to what it is?

This is such a bad explanation of simple physics.
