SUMMARY
The discussion clarifies that a pin support can indeed resist both vertical and horizontal forces, but the direction of the reaction forces is determined by the applied loads and the equilibrium conditions. The confusion arises from misinterpretation of the diagram, where the direction of the arrows does not dictate the nature of the reactions. It is established that while pin supports can resist translation, simple supports are limited to vertical reactions only.
