WebIf the wall thickness of the shell (t) is less than 1/10 to 1/15 of the diameter of the shell (d), then it is called a thin shell. On the other hand, if the wall thickness of the shell is greater than 1/10 to 1/15 of the diameter of the shell, then it is said to be a thick shell. WebA thin cylinder contains fluid at a pressure of 500 N/m 2, the internal diameter of the shell is 0.6 m and the tensile stress in the material is to be limited to 9000 N/m 2. The shell must have a minimum wall thickness of nearly A. 9 mm B. 11 mm C. 17 mm D. 21 mm Test: Thin Cylinders & Thick Cylinders - 2 - Question 7 Save
