It explains the use of torque in statics problems. The angular momentum is equal to the product of the linear momentum and the radius of the path. The chapter presents the law of conservation of angular momentum. If no net external torque acts on an object, the angular momentum of the ...

1 from O and having linear velocity v1 then the linear momentum of A is m1v1=m1r1ω. The angular momentum of A about O is defined as the moment of its momentum about O. Hence, angular momentum of A=r1m1ωr1=ωm1r12. Therefore, total momentum is...
Because the angular momentum L of a rigid body is the sum of angular momenta of the individual particles that comprise the system and because any torque applied to a particle in the system is a torque applied to the system, Equation (7-30),∑τ = dL/dt, applies to rigid bodies. Show...
angular momentum of m 1 is m 1 vR& that of m 2 is m 2 vR. At that same time, angular momentum of pulley is MvR. Total angular momentum: L tot = m 1 vR + m 2 vR + MvR • External torque comes solely from weight of m 1 , m 1 g. So, ∑τ ext = m 1 gR. Newto...
pair is zero, only the torque from external forces remains. (10 - 9) ext d L dt τ = ∑ The external torque acting on a system of particle is equal to the time rate of change of the total angular momentum of the system. 10-2 Systems of Particles 1. Definition of angular mo...
