For example, a telescope with no damping at all allows each cylinder to move
to its maximum limit before the next cylinder moves. If the cylinders have
damping values assigned, then each cylinder causes its parent to begin moving
before it reaches full extension.
Setting a Joint to Spring Back
When a joint resists motion, it also has a tendency to return toward its at-rest
position. You simulate this by setting Spring Back tension in the joints. As
the joint moves further from its rest position, an increasingly larger force pulls
the joint back, like a spring.
When you set Spring Tension higher, the spring pulls harder as the joint moves
farther away from its rest position. Very high settings can turn the joint into
a limit, because you can reach the point where the spring is too strong to
allow the joint to move any farther.

Setting Joint Precedence (HD Solver)
You set Joint Precedence to control the order in which joint calculations are
applied to the kinematic chain. When an IK solution is calculated, the result
is dependent on the order of calculation for each joint.
