Have you ever wondered why some people can walk on tightropes without falling off?
The secret lies in the way they position themselves on the rope.
Whatever positions tightrope walkers adopt on the tightrope, they would do it such that their centre of gravity is always in line vertically with the point of contact (pivot) between their legs and the rope.
In this manner, their weight cannot exert a moment about the pivot (because perpendicular distance = 0) to cause them to turn and topple to either side of the rope!
Can you see how useful the physics principles you learn in school are!
