Coordinates xyz are fixed to the ring as shown and the frictionless pin at A is aligned with the x-axis. The vertical shaft precesses about the Z-axis with constant angular velocity 2 = 1 rad/s. (a) At a particular moment when 0 = 30° and = 4 rad/s, find the value of Ö . This comes from a sum of the moments about the x-axis. Do not neglect gravity.

- In the helicopter shown; a vertical tail propeller is used to pre- vent rotation of the cab as the speed of the main blades is changed. Assuming that the tail propeller is not operating determine the final angular velocity of the cab after the speed of the main blades has been changed from I80 to 240 rpm. (The speed of the main blades is measured relative to the cab, and the cab has a centroidal moment of inertia of 650 lb.ft.s2. Each of the four main blades is assumed to be a slender rod 14 ft weighing 55 lb.)arrow_forwardJust a, b, and c please.
