The spring has a spring constant of 20 N/m and an unstretched length of 1.5m. each rod has a length of 3m and a mass of 10kg. The disk has a mass of 5kg, a radius of .5 and rolls without slipping. The system starts with an angle between the spring and rods of 60 degrees, determine the angular velocity of the rods after it has dropped to a 30 degree angle.

ends of a flexible cable. The cable passes over a pulley of 100
cm diameter. The weight of the pulley is 600N with a radius of
gyration of 50cm about its axis of rotation. Find the torque
which must be applied to the pulley to raise the 8KN weight

- HW2 A uniform disc of 80 mm radius has a mass of 2000 g. It is mounted centrally in bearings that maintain its axle horizontally. The disc spins about its axle with a constant speed of 550 r.p.m. while the axle precesses uniformly about the vertical at 50 r.p.m. The directions of rotation are shown in the figure below.

At maximum speed, the vertical distance from the center of the sleeve to the pivot was 500 mm. For another case, it can be seen that the height of the governor will reduce to half values when the ball masses are replaced by three-time larger from the first case.
