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.
For the volume of the small cylinder, it would be 1.5 cm instead of 3 cm since 1.5 cm is the radius
thank you very much i would love to see more of these videos

I think its 58.64 not 56.64 for the volume displaced
hey, can someone explain how the hydrostatic force equal to the weight of missing water ?
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 ?
