Question:

Large concrete cylindrical shells sealed at each end are to be used in the construction of an offshore oil drilling rig. These cylinders are floated out to the site and then uprighted to form part of the structure. The cylinders are 20m in diameter and, when floating in the horizontal position (axis horizontal), sink to a depth of 14m (that is, their height above water is 6m). What will be their height above water when erected? The cylinder length is 40 m. Take γ-9810 N/m3
