Problem 3: A concrete block is lifted by a hoisting mechanism in which the cables are securely wrapped around the respective drums. The drums are fastened together and rotate as a single unit at their mass center at O. The combined mass of the drums is 150 [kg], and the radius of gyration at O is 450 [mm]. A constant tension of 1.8 [kN] is maintained in the cable by the power unit at A Determine the vertical acceleration of the block and the resultant force on the bearing at O. 300 mm P-1.8 kN 600 mm m 150 kg ko = 450 mm 45° 300 kg
