Question on the 3D Kinematics equation.

Click For Summary
The discussion centers on understanding the transition between two equations in 3D kinematics, specifically how the terms in parentheses of equation (14) relate to equation (15). Participants express confusion about the Transport Theorem, which is crucial for this transition. It is suggested that the theorem, which connects time derivatives in rotating coordinate systems, should be referenced in the textbook used. The relevant sections of the textbook, including diagrams and explanations of the Transport Theorem, are located on pages 4 and 5. Clarifying these concepts is essential for grasping the kinematic equations discussed.

How exactly did the terms in parenthesis of the equation (14) become (15)?

I don't even know what the Transport Theorem is about?

What textbook is this? Since the text directly references Transport Theorem I would expect it to be described earlier. Perhaps look in the index or try compare with transport theorem where you can see it relates the coordinate-wise time derivative of a point coordinated by two different coordinate system that rotate relative to each other.
 
My idea is that I want to use immerse Whitetail Antlers in a fishtank to measure their volumetric displacement (the Boone and Crockett system is the current record measurement standard to place in a juxtaposition with) I would use some sight glass plumbed into the side of the tank to get the change in height so that I can multiply by the tank cross-section. Simple Idea. But... Is there a simple mechanical way to amplify the height in the sight glass to increase measurement precision...
