Angular Acceleration when accounting n-reference frames

Click For Summary
The discussion focuses on the equation for angular acceleration when three reference frames are considered and seeks to extend this to n-reference frames. Participants are exploring how to derive a generalized equation that incorporates multiple reference frames in angular motion. The conversation emphasizes the complexity of the mathematics involved in transitioning from three to n-reference frames. Clarifications on the underlying principles of angular acceleration and frame transformations are also discussed. Understanding these concepts is crucial for accurately modeling systems with multiple reference frames.

Hello,

I understand the equation that describes the angular accelerator when 3 reference frames are involved is:

Now I would like to ask what is the resulting equation when accounting more than 3 reference frames, i.e. when n-reference frames are involved.

Thank you.
 
Hi all, I've looked through design manuals (SDP/SI, Gates, Naismith) and textbooks like Shigley's, but haven't found an equation linking initial belt tension to pulley center-to-center distance for a timing belt. I understand initial tension is typically based on the applied load, but I'm curious: A) Is there a known equation relating tension to C-C distance? B) If not, how might one go about deriving it? Thanks in advance!
