And so all we have to do now is to calculate the moment of inertia of the system, and then we can predict what the period — of this pendulum is going to be — which is not my goal.
Sleep inertia (SI) defines a period of transitory hypovigilance, confusion, disorientation of behavior and impaired cognitive and sensory-motor performance that immediately follows awakening.
Methods According to vibration theory the relationship between the period of a torsional pendulum and the moment of inertia of a part is established and the test method is given.
