SM-1420 Three Hinged Arch Apparatus

In this apparatus two equal arches are used to develop a flat bridge deck .The arches are hinged at their outer most ends and at the crown hinge in the centre, creating the three hinges. Known weights can be applied on two different locations to investigate the pattern.

Hinges with fixed supports can absorb vertical and horizontal forces. The crown hinge at the center renders the entire arrangement statically determinate.
