Problem II. A proposed elevated tank for a certain community has a diameter of 72 inches and a height of 120 inches. It is to draw water by a pump from an aquifer down below the ground. Two steel hoops, 24.4 in? in cross section, are installed around the tank, one at the bottom and one at the top, to prevent the bursting of the tank by the water pressure inside. (Use unit weight of water, ywater = 62.4 lb/ft) a) Compute the internal stress at the bottom of the tank (in psf). b) Determine the tensile stress at the top (in psi). c) Determine the tensile stress at the bottom (in psi).
