A body A of weight 10 kN is connected to an another body B of weight 50 kN, resting on a smooth table of weight 200 kN through an inextensible thread, passing over a freely rotating pulley mounted don a corner of the table. Find the vertical component of the reaction of the ground on the table when the bodies A and B are in motion. Does the reaction change with time? The system is shown in Fig. 6.
