...of rotation. 17. Varignon's Theorem. — The algebraic sum of the moments of two concurring forces, **about any point in their plane, is equal to the moment of their resultant about the same point.** let M be any point, and p, q and r be perpendiculars from the point upon the lines of action of the... | |
