WebDifference between a thin cylinder and a thick cylinder. The cylinder whose thickness is less than 1 10 to 1 20 of its diameter, that cylinder is called a thin cylinder. The cylinder whose thickness is more than 1 20 of its diameter, that cylinder is called a thick cylinder. Suggest Corrections 6 Similar questions Q. WebThe theoretical treatment of thin cylinders assumes that the hoop stress is constant across the thickness of the cylinder wall (Fig. 6.1), and also that there is no pressure gradient across the wall. Neither of these assumptions can be used for thick cylinders for which the variation of hoop and radial stresses is shown in (Fig. 6.2),
