**An interrupted pendulum is one in which the string strikes a rod directly below the pivot point causing the pendulum bob to deviate from its previous circular trajectory into a trajectory of a smaller radius. Depending on the original angle of displacement θ and where the rod is placed relative to the total length of the string, the bob may or may not wind itself completely around the rod.**

Calculate the minimum distance x in terms of L and θ that will cause the pendulum bob to completely wrap around the rod. You should be careful here – the bob must have sufficient energy to completely circle the rod, and not enter a projectile motion pattern of free fall.

Any solutions is appreciated, steps to solutions are very valuable. Thanks!
