that is going to be challenging, to be honest. First, Fusion does not support dynamic changes in a single solid component/body. So, your current approach is not going to get here. You might be able to model each little section as a component, and put a ball joint in between each, but my guess is that that approach is not destined to bring you a lot of joy. Long chains of joints like that are a problem, and ball joints themselves are sometimes difficult to control. It might be worth a try, but I'm not too hopeful. Sorry not to have a better answer...
