Is there anything different between 16-147 and 16-142 about what we have to take into account or procedures? I got 16-142 right and followed the exact same steps, but can't get 16-147 right." |
I got those same answers. I think the problem is that in both eq. 16-24 and eq. 16-27, the omega is the angular velocity measured from the fixed reference. The omega they give us for disk B (0.5 rad/s) is relative to the arm. I don't know how to make this angular velocity "global"
So ... given a relative angular velocity, how do you make it an absolute angular velocity?
