4-1. (5) Consider the Boeing 787 Dreamliner. Problem 4-1 From www.boeing.com/commercial/787. We want to perform a quick assesment of the inertia properties of this airplane. This means that in the following we are looking for qualitative (as oppose to precise quntitative) answers, which will result from making some simplifying assumptions about the aircraft. In answering, please carefully explain your modeling assumptions. 1. Determine the principal axes of inertia of the aircraft. 2. Which principal axis has the largest moment of inertia around it?
