A ceiling/table fan is generally stationary. Hence it satisfies the condition for translational equilibrium. When the blades of the fan rotate with constant angular velocity, their angular acceleration is zero. Hence, it also satisfies the condition for rotational equilibrium. Therefore, a fan rotating with constant angular velocity is in mechanical equilibrium
