Homework Statement Considering the concepts of Rigid Body/Angular Momentum/Torque A body rotating with respect to an axis that passes through ANY point P, whose acceleration could be different to zero. Prove: Ʃτ(ext, p) = dL(rel_p)/dt + ρ(cm) x Ma(p) Ʃτ(ext, p) = dL(rel_cm)/dt +...

Considering a Rigid Body/Angular Momentum/Torque We know that Torque(ext) = dL/dt Now with respect to stationary point S: L(s, cm) = Ʃ(ρi x mivi) and that dL(cm)/dt = Ʃτ(ext, CM) Now with respect to ANY point, P, that is accelerating: L(s,p) = L(cm) + ρ(cm) x Mv(cm) And hence...
