2.[20p]. A cylindrical tank of inside diameter Dā=2.75m and wall thickness of 6mm is filled with water to a height, h2 = 8 m. The height of the cylinder (H) is 10m and the density of the cylinder material (pm) is 2.8 x 10³ kg/m³. Calculate the axial stress, Ļy and the circumferential (hoop) stress (ĻĪø) at the bottom of cylinder. Hint: water pressure (N/m²) p = pwhg, g = 9.81m/s². pw = 1,000 kg/m³, h(m).
