A system of four non-coplanar weights is arranged on a shaft (the angles and lengths on the figure are arbitrary), as shown in Figure 1. The shaft rotates at 200

rpm, LB =1200 (mm.) Assume the following data: For the unbalanced System, Figure 1 (Without the Two counterweights(ma and mB, at planes A & B respectively), calculate the magnitudes and relative angular orientations of the bearing reaction at C & D, Fill your answers in the following table Determine the masses (ma and mg) and angles of the counterweights incorrection planes A and B needed to dynamically balance the system, at RA400 mm., and Rg = 500mm. The correction planes are Lg =1200 (mm.)apart. Fill your answers in the following table:
