Info

A wing generates more lift when it is moving faster so point A is generating more lift than point B. The two forces F A and F B can be represented by a single force and a single couple C. With this simple representation of the forces acting on the boomerang we can give two reasons why it moves on a circular path: Sunday, May 30, 2010 14
1. A constant centripetal force F produces circular motion with velocity on a radius such that: F = mV 2 /R (1) where m is the mass of the boomerang. 2. A constant couple C acting on a gyroscope spinning at angular velocity ω causes steady precession at rate Ω such that: C = JωΩ (2) where m is the mass of the boomerang and J is its moment of inertia.
