## Applied Mechanics and Graphic Statics Varingon’s theorem of moment’s states

Arithmetical sum of the moments of two forces about any point, is equal to the moments of their resultant about that point
Arithmetical sum of the moments of the forces about any point in their plane, is equal to the moment of their resultant about that point
Algebraic sum of the moments of two forces about any point, is equal to the moment of their resultant about that point
Algebraic sum of the moments of the forces about any point in their plane, is equal to the moment of their resultant about that point
