A rope is passed round a stationary horizontal log fixed at a certain height above the ground. In order to keep a load of mass `m = 6` kg suspended on one end of the rope, the maximum force `T_(1) = 40N` should be applied to the other end of the rope. Determine the minimum force `T_(2)` which must be applied to the rope to lift the load.
