How do I Pin with physics

I am trying to create a ferris wheel. I had an object rotate and other objects (platforms) pinned to the rotating object with a soild behaviour. When I tested, the platforms did not sway, they just moved with the rotating object (fixed in place, static, but moving with the object).

How can I get the platforms to move about, sway etc when pinned and with the pysics behaviour?

I have no experience with the physics object myself, but the following seems relevant.

Create limited revolute joint

Hinge two physics objects together, so they can rotate freely as if connected by a pin. Limited revolute joints only allow rotation through a certain range of angles, like the clapper of a bell. An image point can also be specified to connect to a specific part of the object. Note that an image point of 0 specifies the center of gravity of the object - if you intend to connect to the object origin, use -1.

oosyrag thanks, I checked it out. I just have to mess with it until I get the result I want.
