What if there was no displaced volume (perfect cylinder filled with water)? then forces up would be 0, hence FB+30kN=0? the force of the bolts would be negative?
just think about the buoyant force. consider the volume 'replace with air' be in water. the buoyant force has a magnitude equal to the weight of the fluid displaced by the body and is directly vertically upward.
thank you very much i would love to see more of these videos
For the volume of the small cylinder, it would be 1.5 cm instead of 3 cm since 1.5 cm is the radius
He did that part correctly. He knew he was using the diameter instead of the radius, hence the pi/4 instead of just pi.

hey, can someone explain how the hydrostatic force equal to the weight of missing water ?
I think its 58.64 not 56.64 for the volume displaced
why is there a 1/4 in the volume of cylinder? isn't the formula for cylinder just pi(radius)^2h?
Hmm
It's because he used the diameter not the radius
why you found the space volume i dont understand. Can we just calculated the water volume ?
