Question

obtain an expression realating the torque with angular acceleration for a rigid body ​

Answer 1

Answer:

Let F1, F2, F3, …., Fn be the tangential force acting on particles of masses, m1, m2, m3, …, mn respectively. Thus, when a torque rotates the body with uniform angular acceleration of 1 rad/s2 then M.I of the body about a given axis of rotation becomes equal to torque acting on it
