Targ S.M. 1988 D4 option 10

Vertical shaft AK, rotates at a constant angular velocity of 8c⁻¹. A weightless rod 1 of length L₁=0.4m is rigidly fixed to the shaft; with a point mass m₁=0.6kg at the end and a homogeneous rod 2 with a length L₂=0.6m; having a mass m₂=4kg; both rods lie in the same plane. Neglecting the weight of the shaft, determine the reactions of the thrust bearing and bearing.
