1) Three small spheres are rigidly mounted to a horizontal shaft with rotates with angular velocity omega as shown. Neglect sphere radii, ignore gravity. Spheres have masses m1, m2 andm3 as shown. a. What is the angular momentum HO about O the center of the coordinates shown? b. At this instant, what is Ax , the x component of the bearing force at A to offset the dynamic imbalance? Note that you are NOT asked to find any other forces (Ay, Ox, or Oy) in interest of time.
