from 3:40 on, why didn't we use the fluid for W and the wood for Fb?

As shown in the free body diagram, W is the weight of the WOOD and Fb is the buoyancy force. Thus, Fb is the weight of the WATER displaced by the wood (Archimedes principle). That is why I used the specific gravity of wood for W, and the specific gravity of water for Fb. I hope that helps.

Why u supposed that Fb in this location maybe it is in another location

@FluidMatters Жыл бұрын

F_b acts a the centroid of the submerged volume (half way down the submerged section of the rod) because it is the displacement of fluid that produces the buoyancy force.
