Reply To: How will the reaction moment on the support be distributed in terms of forces in this model?

[Rameez_ul_Haq]

the primary purpose for me of opening this thread here was to basically understand the difference between the reaction moment (arising from a static equilibrium model) and a moment arising from a moment arm in a Rigid Body motion.
Please observe the model below, showing a Rigid Body motion about the Z axis of revolute joint.
How is this moment different from the reaction moment that we see on the fixed support of a cantilever beam (subjected to shear force on the other end) in a static equilibrium model? Both models have a shear force at one end and a distance D, and when F is multiplied by D, it gives the same moment (rather it be reaction moment or moment arising from moment arm). So what would be the difference between these two moments.
