Hello! How do I calculate the maximum possible rotational speed of a thin walled hollow cylinder? In other words, at what rotational speed will it explode due to centripetal force? This picture shows the plane of rotation: http://www.ithaca.edu/faculty/mcsullivan/PH117/CTs/CT-ParallelAxisThereom-IMAGES/HollowCylinder.gif All I need to know is: Tensile strength of the material of the cylinder Radius Density of the material of the cylinder Nothing more, right? Because the cylinder is hollow and thin walled it shouldn't be necessary to integrate, right? Thanks in advance!
