👉Different Between Hinge, Roller, Fixed Support
📌Roller Support:
Allows rotation and horizontal movement, but resists vertical movement. It provides one reaction force.
📌Hinge (Pinned) Support:
Allows rotation, but resists both horizontal and vertical movement. It provides two reaction forces.
📌Fixed Support:
Prevents rotation and all horizontal and vertical movement. It provides three reactions: horizontal, vertical, and moment resistance.
