Join Aaron F. Ross for an in-depth discussion in this video Creating a Hinge constraint, part of Maya Dynamics: Creating Simulations (2012).
Currently, we've got Rigid Body nodes applied to all these spheres and we…attached them to Gravity nodes and now they're falling.…You want to keep them in place. I'll select one of these spheres, and in the…Dynamics menu set I'll go up to Soft/ Rigid Bodies and you'll see various types…of constraints listed here.…In fact they're all the same node type with different settings.…In this case, I want to choose a flavor Create Hinge Constraint, select that.…And now inside this sphere located right at its center of mass is a hinge.…
I'll get in closer by pressing F key and hit the 4 key, so we can see wires.…Here is our wireframe view, and that's the hinge.…I've built my scene, so that the hinge will be oriented in the correct direction…to begin with and I will move that up.…Let's go out to the front view and move that up in the front view, so that it's…right at the top of those cylinders there.…I don't need to rotate the hinge in this case.…It should work just fine.…
The object will swing in this direction.…
