Extracted text: A rectangular tank with a square base and open at top and left side designed to manufacture from sheet steel as shown in figure 2. There is a circular hatch onto bottom with diameter of 0.6 m as shown. On the left side of the tank there is a rectangular door with the 0.85m width, which is held by a force F, at the top of door, also a hinge at the point A, controls it (as shown). The tank filled with the oil of density 820 kgm³. Calculate the following: • The hydrostatic force subjected to the hatch. • The hydrostatic force acting to the side door. • The reaction force Ra at the bottom of the hinge.
