6 cans containing soda made out of aluminum ( E = 69 GPa, σY = 240 MPa ) material are shaken. Shaking them creates an internal pressure of 0.14 MPa in each can. A uniform load of W is applied to the cans through a plate which has a negligible weight. The inner diameter of each can is 2R = 62 mm, the wall thickness is t = 0.25 mm and the length is L = 112 mm.
