Then I really do not understand how the rotational velocity of the shoulder and the translational velocity of the elbow are related to each other and how they result in the rotatinal velocity, maybe I miss something really obvious here, but right now, I can't see how they result in the...
Thanks, that might indeed be the situation, my main problem is really that I am not sure if I understand the descprition of the problem.
What also confuses me is what rotation of forearm relative to space means in this context the velocity of on specific point on the forearm or if it refers to...
Homework Statement
Suppose you are standing uptight with your right arm stretched out straight in front of you, palm down, the upper arm rotating rightward relative to space at 2 radians/s and the elbow flexing in the horizontal plane at 2 radians/s. What is the rotational velocity of the...
