And you still fail, time after time, to show us how the torque works according to what you say. A step-by-step description, a diagram or even a simple video shot with a cellphone would probably be enough. And another point: why does this "torque" vary only on the location on Earth, not really on the dimensions, weight etc. of the pendulum? REs have provided a simple and plausible explanation for this. What is yours?
