- TL;DR Summary
- I am a bit confused when to use the Euler equations and consider body fixed reference frame and when to just consider a fixed reference frame

Hello I am studying mechanics and I have been reading about having the reference frame fixed at a certain point, body fixed and also the gyro equations.

I an identify the gyro case easily as I am looking for an AAC body which rotates about an axis.

I am confused about the other two cases in which types of problems I should apply a body fixed reference frame.

What I understand in 2D it's easier not to use the body fixed reference frame. However, I am not that sure for 3D cases

Can someone give me an example or an explanation, thank you.
