Question

proof torque=i alpha,where i is the moment of inertia and alpha is the angular acceleration.

Arun · Accepted Answer

The force acting on a particle of mass m1 situated at A, at a distance r1, from the axis of rotation = mass x acceleration = m1 x d/dt(r1ω) = (m1 r1)dω /dt= (m1 r1)d2θ/dt2The moment of this force about the axis of rotation= Force x perpendicular distance = (m1 r1)d2θ/dt2 x r1Therefore, the total moment of all the forces acting on all the particles or τ = Iαwhere ∑ m1r12 = moment of inertia I of the rigid body and α = d2 θ /dt2 angular acceleration.
