The drum and shaft shown in Figure 9 are welded together, and have a mass of \( 60 \mathrm{~kg} \) with mass centre at \( \mathrm{G} \). The shaft is subjected to a torque (couple) of \( 120 \mathrm{Nm} \) and the drum is prevented from rotating by the cord wrapped securely around it and attached to point \( C \). Calculate the magnitudes of the forces supported by bearings \( A \) and \( B \). Dimensions in millimeters
