The videos below show the force and torque FEM loads acting on the pendulum (left) and on the bar (right). Note that, despite all these vectors are rendered using the same scale, their magnitudes change when we compare the action and reaction FEM loads. This is a direct result of the difference in mesh node density between the two parts: if the MbD load is distributed among a higher number of FEM nodes, the magnitudes of the resulting individual FEM loads will be reduced. In this case, MbD loads are distributed among a larger number of nodes in the pendulum than in the bar, so that the magnitudes of FEM loads on the pendulum are lower.
