Hydraulics Solution Sheet 3 – Forces on submerged surfaces
... The force in the direction of gravity is equal to the weight force on the fluid which would occupy a volume between the surface on which the force is to be calculated and the plane of the free surface. That is, it is the region between the upper hemisphere, and the level of the water surface, which ...

Newton`s Laws Of Motion
... Ans: An important point about third law is that action and reaction forces act on different bodies. So here the point is that the man exerts some force but not on himself, but on earth and in reaction earth applies same force over him. The mass of earth is very high as compared to man and so the acc ...
