I have modeled a two piece bridge in in the center is a hollowed out cylinder with a stake though it and a curved end to prevent it from coming apart. In Unity I am trying to make a broken bridge effect. I want the furthur out piece to pivot on the stake to fall downward but if some one were to get hold of it they could pull that end up and it would pivot on that steak to.
You’ll want to check the script reference for Joints - it sounds to me like the type of connection you’re looking for is a joint.
Here’s the hinge joint, probably the one you’re looking for: Unity - Manual: Hinge Joint component reference
Also try tutorial sites. 3DBuzz has a good section on joints in their physics videos: http://www.3dbuzz.com/vbforum/sv_videonav.php?fid=504655656a7ab401656d5c2bed758fa1
