Knuckle Joint:
A knuckle joint is used to connect two rods under tensile load. This joint permits angular misalignment of the rods and may take the compressive load if it is guided.These joints are used for different types of connections e.g. tie rods, tension links in the bridge structure. In this, one of the rods has an eye at the rod end and the other one is forked with eyes at both the legs. A pin (knuckle pin) is inserted through the rod-end eye and fork-end eyes and is secured by a collar and a split pin.
