I'm not sure if this should be in Physics or HMWK Help. If it is not in the right place, please move it. In my Concep. Physics class, we've been assigned a project: We have to build a 21 cm. tower that can support a general baseball at 21cm above the surface of what the tower is on. We are to do this with 13 sheets of regular 8 1/2" x 11" paper ONLY. Nothing else. This is my idea: 1.) Take cut an 11" strip from each sheet of paper that is between 1/2"-1" 2.) Fold each paper such that it forms a box. Each box growing larger as it nears the surface which the tower is on. 3.) Tie width of each box with the strips of paper. In doing so, you would be forcing pressure to go in opposite directions inside the box, and increasing pressure inside the box. The point of this is that, when the baseball is placed on top of the tower, it won't force the boxes to fold in. Does that sound like a good idea? Any suggestions?
