Product description
A person stands in the center of the Zhukovsky bench and rotates with it, making 30 rpm. The moment of inertia of the human body relative to the axis of rotation is about 1.2 kg m. A person holds two weights weighing 3 kg each in his outstretched arms. The distance between the weights is 160 cm. How will the system rotate if a person lowers his hands and the distance between the weights becomes 40 cm? The moment of inertia of the bench is 0.6 kg m2; Neglect the change in the moment of inertia of the hands and friction.
