Balance at center of gravity

If you take a 3x5 card and attach a push pin through the upper left corner of the card into a bulleting board the card hangs, or dangles, at angle. How do I model this in fusion.

I've drawn a cylinder and made a fixed joint to the root, or origin.

I've drawn a prism and made a revolute join so the the prism hang vertically. The prism rotates around the cylinder as expected. When I change the joint origin, the prism still rotates as expected, but it also still hangs plum unlike the card on the bulletin board.

I've applied the center of gravity, but where and how do you apply gravity?

How do you model this in fusion?

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Have you tried this with Event Simulation?  (I don't know if it will work or not.)

I can't seem to make it move in simulation....... Never have been able to get simulation to work. Never seemed to need it.

You will need Autodesk Inventor Professional for this Dynamic Simulation.

Kinda what I thought. I saw a similar post concern a marble racer. I thought things might have changed in the intervening years. If I "had to have" the ability to do such simulation, should I ditch fusion for Inventor? I understand inventor is quite different. There is a top down, general to specific, methodology in fusion vs a bottom up approach in inventor, Then the joints are different.

What do you do? Do you use both?

Nothing much has changed in the 5+ years that I have been following it.

It does not meet my needs - I only follow it to keep aware of what Autodesk is attempting.

Top down assembly modeling can be done just fine in Inventor.

Inventor is a professional program and deserves (requires?) a professional level of training.
