A loop of rope is whirled at a high angular velocity`omega`, so that it becomes a taut circle of radius r.
(a) Find the tension in the rope it the linear mass density of the rope is `mu`
(b) A kink develops in the whirling rope. Under what condition does the kink remain stationary relative to an observer on the ground?

Answer

(i)`mur^2omega^2` , (ii)The loop rotates is opposite sense of the rotation of the kinck
