Hi everybody
I'm wondering about a simple plot, if I suppose the correct interpretation.
It's a simple test about Bicipes tendon force vs elbow flex (0 - 130 degree).
In position 0 degree, the force is equal to 600 N. This means tendon force of that part of muscle (Bilong) can develop F=600 N.
Supposed: [ F = m* a ]
Is F direction along tendon lenght, right?
Are m and a reported to the muscle part connected to the tendon ?
So if I sum all bicipes muscles in the model (3 types) , I get in the same position F = 2000 N. Is it not too much comparative in real life ?
thanks very much in advance.

Yes.Is F direction along tendon lenght, right?
Whether a simulated muscle is unreasonably strong also depends on the muscle's path, since the ability of a muscle to generate a joint moment depends on its moment arm. Please see "What is a moment arm? Calculating muscle effectiveness in biomechanical models using generalized coordinates" (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4404026/) for details.Are m and a reported to the muscle part connected to the tendon ?

Hi,
in the plot "biceps Force vs Elbow extension" I don't understand why the curve decreases from 60
I have the same question for the curve "tendon-force vs flexion" in tuto 2.
thanks very much in advance.
