No score will be given after two days. ...........................................................................The formula for the cylinder’s inner diameter assumes that the stress within the cylinder is uniformly distributed throughout the wall thickness. In fact, the circumferential stress in a high-pressure thick-walled cylinder is not uniformly distributed along the wall thickness; the maximum circumferential stress occurs at the () wall of the cylinder. For a circular plate with simply supported edges, under internal pressure the maximum stress occurs at ( ). For a circular plate fixed at the periphery, the maximum stress occurs at ( ). ...........................................................................Answer: Inside ； center ； Edge. Comment: This is the most common stress distribution in thick-walled cylinders, and it tests designers’ understanding of basic stress distributions as well as their grasp of fundamental concepts. Comment: It examines the effect of boundary conditions on the stress distribution in a flat head under various connection scenarios with the cylinder body.
