What body mechanics define Internal Strength in your personal Opinion?
What Physical structures are trained?
What is the reaction of those structures to input/output of force (application)?
I look forward to hearing some detail on this.
thanks in advance

Mean Answer to Question 1: None.
Not that no body mechanics are involved in the training. But they don't define IS. IS comes IMO from Yi-Control/Direction. (Of course the body has to be conditioned to transmit force.) Sorry for not pushing hope for external vocabulary understanding of internal.
Question 2 seems more useful to me. (but it's too late now to think hard of what to say, sorry)

Yes. I've explained before in previous threads that it is anatomically and physically impossible for a human being to elongate his head/neck along the longitudinal axis. Therefore, from a purely technical point point of view, the classic admonition to 'raise the crown' is based on a proposition that is false. We also know that anatomy/physiology/physics/biomechanics, etc. have come a very long way since the days when a series of mostly illiterate and uneducated laymen who happened to practice the societally lower class practice of martial arts first came up with their various sayings, admonitions and axioms. However, strict technical accuracy isn't absolutely essential when we take these sayings as the analogies and metaphors that they were always understood to be. In this case, the feeling (kinesthetically and proprioceptively) is such that it feels very much like one's head is stretched and suspended along the longitudinal axis of the body, even if it isn't.
What's actually happening here is that the head is brought into parallel with the transverse plane of the body, and very slight contractions of the erector spinae and trapezius straighten the spine to its full natural length. Similarly barely perceptible contractions of the latissimus dorsi, infraspinatus, rhomboids and deltoids serve to pull downward on the shoulder/pectoral girdle, with the resulting pull on the scapula and clavicle producing a very slight stretch of the trapezius, resulting in a feeling of the head stretching away from the body.

I don't think this is true for Bagua.

The spine rotates as a whole. No twisting or wringing like a towel. Shoulders stay in line with the kua. Torso rotates right and left like the agitator in a washing machine.
Knees stay stable allowing force to come up and be transmitted through the legs to the waist. If the knees wobble or move then a lot of force gets lost.
Back is spread out taught. Shoulders down, connected to the rest of the frame. Not floating up.
Weight is forward in the feet not centered over the heels.
Head is stretched up slightly with the bai hui point as if pulled up by a string. Spine stretched down as if a weight being supported by the hui yin point.
Arms do not push using the strength of the shoulder or triceps muscles.
Ti or lifting force in the elbows and knees.
These are the physical mechanics I look for in someone.
