Hello, guys! Migue79 to bring you all another blog to calculate the force needed to rip the arm off of a normal human as it was deemed necessary here.
Calculation[]
There is this article that was used initially to find the force of ripping a person's arm off. However, while the article cites the tensile strength of a human's glenoid labrum as 6.39 MPa from a previous study, the article messed up the conversion of the area where the force is applied. Therefore, I am going to try and fix that here.
Diameter of arm at shoulder joint: 20cm or 0.2 meters.
Area: 0.0314 m2
Force: 0.0313 m2 * 6.39e6 N/m2 = 200,646 Newtons or 20,453.211 kgf (Class 25)
This will be a reference for any feat involving ripping a person's arm from the shoulder joint.
