Hey I have a physics related question. I hope that it is okay, since it is pretty simple. For torque of an object, it is described as Torque = r * F. For the r vector, if you imagine a book exceeding maximum overhang at the edge of the table, how would you measure the r vector? The book is uniform. I hope it makes sens...
