1. The problem statement, all variables and given/known data so we have this engineering assignment (high school final year) where we have to design an airplane wing and one of the tasks is to (graphically, not all of us can even differentiate let alone mathematically derive it) identify the center of mass of the wing... now, i know how to do it for the PLANE, and i know how to do it for simple shapes like Ls ans such, but how do I do it for a wing? The teacher said that we use the center of mass as a point where we put the weight of the wing on and then we can do moments calculations and find the material/method of joining the wing to the plane. My wing is similar to a 737's wing. 2. Relevant equations 3. The attempt at a solution do i just divide the spans up into trapeziums and then find their centers of mass? then how do i go about finding the center of mass for the WHOLE wing??
