When you hit the performing stage, keep observing your team's progress in case it slips back. For example, a new team member can disrupt the group dynamic, or a new business direction might mean you have to reevaluate your team roles and goals. trichy property developer

"WebForward dynamics Watch on Share Transcript So far we have worked out the torques on a robot’s joints based on joint position, velocity and acceleration. For simulation we want the opposite, to know its motion given the torques applied to the joints. This is called the forward dynamics problem.
