By the time you get to the last can in your six-pack it seems like a good idea to twist the top off like a bottle cap instead of pulling the tab to open it. The unopened can (length L, diameter d, wall thickness t) has an internal pressure P and your twisting causes an external torque T. Draw the element at point A and indicate the state of stress on that element.
