Reply To: Static Structural Analysis, Reaction forces in different coordinate system

[dlooman]

If Coordinate System_Bolt1 is a cylindrical system, X is the sum of the radial forces and Y is the sum of the tangential forces.  Only the cylindrical Z force is comparable to the Global Z and they do match.   So the tangential forces will tend to be large as they are resisting the moment in addition to the reaction force.
