Hi, guys, i am struggling to figure out the answer of below question, please give your suggestions. thanks! Given Cantilever Beam 1 and Beam 2, the right ends are free, no constraint to put them two together. When no force acting on, they will stay together; while when there is pressure difference, what will happen? Are they still keeping together with only the right end slipped? Or the 2 beam are totally separated? How can I get an accurate mathematical model of the problem?
