Question

1. The gear shown has a mass of 10 kg and is mounted at
an angle of 10° to the rotating shaft which has a negligible
mass. (x, y, z) axes are aligned with the principal
directions of the gear and the moments of inertia with
respect to these axes have been measured as Izz =
0.1 kg-m², Ixx = Iyy = Izz/2. If the shaft is rotating with
a constant angular velocity of w = 30 rad/s, determine
the reaction forces at the two bearings at the instant
shown. Neglect gravity.
