Can an object be in equilibrium while having angular acceleration? I did learn about angular stuff last year in physics I, but I forgot a lot of them. Plz help me
No, an object would not be in equilibrium when it has some angular acceleration. In order for an object to be in equilibrium, the object should satisfy both of these following conditions:
No net translational acceleration (you may also call this linear acceleration). Also, according to Newton's second law of motion, as sum of force equals mass times acceleration, no net translational acceleration also means zero net force.
No net angular acceleartion. Also, as sum of torque equals moment of inertia times angular acceleration, no net angular acceleration also means zero net torque.
Remember, in order for an object to be in equilibrium, both of these conditions should be satisfied. For example, if the object satisfies condition #1, but not #2, it means the object is not in equilibrium as it is rotating with acceleration at a particular place. Similarly, if the object satisfies condition #2, but not #1, it means the object is not in equilibrium as it is moving with acceleration although it is not rotating with acceleration.
Hi, thank you for your question.

Does this answer your question?
