one customer asked me what torsional springs are used for and if I could supply an example. I was looking at the wheel of fortune tv show and I've created the example in attach.

Contact was defined between parts to prevent penetration, and then a STEP function on force to simulate a person spinning the wheel.
Finally a torsional spring was used to have the pointer always come back to the initial position.
