Question 1: Thick Cylinders A cylinder with closed ends has an internal diameter of 100 mm and a wall thickness of 50 mm. The cylinder is simultaneously subjected to an internal pressure of 100 MPa and an external pressure of 40 MPa. Young’s modulus is 200 GPa and Poisson’s ratio is 0,3. Calculate: 1) The resultant hoop stresses at both diameters. 2) The resultant internal diameter. 3) The resultant external diameter. 4) The resultant thickness of the cylinder wall.
