- TL;DR Summary
- I have confusion understanding moments of forces and moments of couples in cartesian co-ordinate system
1) are all Moments of forces and Moments of couples free vectors? Can I move the moment vector computed about point O to a new point "point B" without changing the system? To elaborate on the question, suppose Resultant Moment about point O is computed using several forces and the position vectors to their points of action. My goal is to find Moment of the same forces about Point B. If moments are free vectors, I should be able to move the moment about O to the point B without changing the system. but It seems wrong to me.
2) moment of several forces about point S is known and I need to find moment of the same forces about point P, is this doable using the info about point S? i.e; info of position vector from P to S and secondly moment about S?
