More on the equilibrium concept see fig3. 23 in text what is upward force on glass window. A window b hypothetical situation consider i i ii. B the hypothetical scenario the line ab is not moving. 4 horizontal forces consider half a sphere in water e. Fxadue to pacting on caroedsurface a flat surface ater. But fx fxz so even though he is acting on curved area it to force due to p exerted on a is equal. 1 projection of curved surface area on g t a verticalplane. 4 is fyi forces consider half a sphere. Vertical fya no since a in water styrofoam object would float which requires fy fy. tw so fyz fy. Buoyancy buoyancy force a body immersed in a fluid.
