Description
Kinetics of Rigid Bodies 4-24-17 Rigid Body = extended body Direct use of NSL → treat as system of particles. We use two of the equations of systems of particles Where m is total mass and a is acceleration of mass center Angular momentum about mass center Hg' is total angular momentum Centroidial mass moment of inertia Continuous body- sum becomes integral Where r' is the distance of dm from G Some values- uniform m,L rad Uniform disk or cylinder- Uniform sphere- In 2D, These are the equations of motion.
