A system with an axle is pivoted on the centre as shown in Figure 1 below. It is connected with a weight, 5 kg at one end and a wheel with weight 8 kg at the other end. The wheel radius is 40 cm and rotates with a speed 800 rpm counter-clock wise looking from right-side. Determine the precession velocity and direction of the system at vertical axis through the axis centre.
