1. The problem statement, all variables and given/known data I am supposed to examine the effectiveness of a vibration absorber design for a quad copter. Attached is a picture of the quad copter and the design; basically each of the spring dampers would be attached to an arm of the copter. In the case of a single quad copter arm, what would be the primary system and what would be the absorber system? 2. Relevant equations 3. The attempt at a solution I know the absorber system is the spring damper and the base plate. but for the primary system, is it just the arm or should i include the motor and the blades?
