A client bring a valuable sphere to your engineering firm and wants to know if it is hollow or solid. Devise a way to win their multi-million dollar contract without injuring the valuable sphere. (Tapping the ball and trying to hear an echo does not work...) When you have a plan, present it to another group in the class (as if they were your client) in sufficient detail that they can evaluate your proposal and decide if they would hire you.






Devise a way to measure a momment of inertia for a spherical or cylindrical object. When you have a plan, present it to another group in the class (as if they were your client) in sufficient detail (meaning equations!) that they can evaluate your proposal and decide if they would hire you. Each group takes one turn being the client and one turn being the engineering firm. Your client group must be different than the group for which you serve as their client.
