is an object rotating with no net torque present (such as a sphere spinning about an axis of symmetry) said to be in mechanical equilibrium??
No, since there could still be a net force acting on the object.Originally posted by broegger

Mechanical equilibrium in a rotating system refers to a state where the net torque acting on the system is equal to zero. This means that the system is not accelerating or decelerating, and the rotational motion remains constant.
In order to achieve mechanical equilibrium in a rotating system, there must be a balance of forces and torques acting on the system. This can be achieved by adjusting the position, mass, or distribution of mass of the objects in the system.
Mechanical equilibrium is important in a rotating system because it ensures that the system remains stable and does not experience any changes in its rotational motion. This is essential for the proper functioning of many machines and devices, such as motors and turbines.
Mechanical equilibrium refers specifically to a balance of forces and torques in a rotating system, while dynamic equilibrium refers to a balance of all forces and torques in a system, including those acting on objects in linear motion. Dynamic equilibrium can also refer to a state where the system is in motion at a constant velocity.
Examples of mechanical equilibrium in rotating systems include a bicycle wheel in motion, a spinning top, a ceiling fan, and the Earth's rotation around its axis. In each of these examples, the net torque acting on the system is equal to zero, resulting in a constant rotational motion.
