Power transmission

My question is assuming that the kua(s) are opened does that result in neutral equalibrium because the center of gravity is neither raised or lowered, basically by allowing those to be at the same level at the same time then potential energy, rotation, and reveloution are possible because if something with neutral equilibrium moves those around with follow, and then using joint rotation, you are using angular velocity which then turns into linear velocity, almost like a series of rotations(angular velocity occur) starting from the bottom up then transmitted to linear velocity, therefore if you have these continous angular velocity it is like a wheel continuously spinning around the axis while taiji has numerous axis points that are rotating.
