Webb25 juli 2024 · The easiest method is to buy pre-cut kinesiology tape specifically for the knee. This is called a Y-strip, as it looks like an extra wide piece of tape that's partially cut in the middle. Start wrapping about 3 to 4 inches above the knee. Bring the tape down so the split goes over the kneecap, exposing it as the tape goes on either side. WebbYou’ll understand how to use the Direct Stiffness Method to build complete structural models that can be solved using Python. You’ll have your own analysis programme to identify displacements, reactions and internal member forces for any truss.
