Hey,

I just fnished med school and I have been conduction biomechanical research for the past 3 years now. I am currently working on a project plan and I am encountering the following problem:

We would like to measure compression across a joint, using partially threaded screws. For the standard procedure, 3 screws, more or less orthogonal to each other, are used. From a mechanical point of view, a second screw, orthogonal t the first one, should not add any any compression as the energy is absorbed by the first screw.

I would like to ask you 2 questions:
1) which law / mechanical rule has to be applied in the case mentioned above
2) i would like to illustrate this in a presentation ... any ideas?

Thank you for your help in advance!

Kind regards,

Sebastian
