Hinged Iron Gate

Hinges are mechanical bearings that are used to connect two swinging objects or points to one another and give them the freedom to move relative to each other. Hinges have limited movement, allowing the joint to move only at one angle and restrict the other movements of swinging parts.Most hinges consist of three basic parts: leafs, a knuckle and a pin. Leafs are the rectangular-shaped plates on the sides of a hinge. A knuckle is a cyldrical-shaped tube that's created when the leafs are joined together. A pin is a solid metal rod that's inserted through the knuckle to interlock the leafs.
