This principle states that the buoyant force has a magnitude equal to the weight of the fluid displaced by the body and is directed vertically upward.
Using this principle one can find the buoyant force on an immersed object by enclosing the body with a parallelepiped and then removing the body. Sum the forces acting on the parallelepiped and the resulting force is the buoyant force. This principle states that the buoyant force has a magnitude equal to the weight of the fluid displaced by the body and is directed vertically upward. FTP, identify this principle named in honor of a Greek mathematician who first noted the basic ideas associated with hydrostatics.
