A table tennis stroke is a swing, and there is a delay in transmission of hip motion to arm motion in that instance. Furthermore, there is a body weight component that enables you to transmit force through the joints to the arm.
TBH, rather than a debate on whether or not the arm continues to...
Oh my goodness! I didn't realize it was that complicated.
Is it not possible to use a greatly simplfied model that assumes a simple hinge joint and evenly distributed connecting tissues spread across its width?
In the first instance, I'm simply trying to work out the increase in stress on...
Oh I think just a very simplistic level of accuracy will be more than adequate for exploring the principles in the grossest sense.
I'm really looking for a basic understanding about the transmission of force down the various joints.
I've heard about various styles that are created around a...
I'm trying to work out the science of a simplified model of the human body, and I would appreciate your help on some of the basic formulae.
If I have a bar (representing the shoulders), which has a central pivot point, connected by a unrestricted hinge to a rod (representing the upper arm...
Using simplified models for the muscles, ligaments, and cartileges, do you think that it's feasible to construct a scientific model for all of the interactions of motion that occur in the human body in order to calculate optimal transmission of force whilst moving, striking, and evading...
I'm trying to calculate the stress placed upon knee joints by low karate stances.
If I assume a body weight of 200 pounds, with a shin length of 18 inches and a thigh length of 24 inches, how can I calculate the force placed upon the knee joint when the thigh is:
verticle above the shin...
I'm a karate instructor desperately trying to find a model or formula that explains what happens to the to speed and acceleration of a limb under varying conditions.
If you assume that a limb has a travel distance of 3 feet, moving from stationary, and the limb weighs 5 kilos.
If I assume...
