Hello. I'm currently entering into a Physics II class at the start of my third semester at UCONN (my first semester was introductory modern physics - kinetic theory, hard-sphere atoms, electricity and magnetism, scattering, special relativity, Bohr model, etc), and finished Physics I off with torque and angular momentum before icing it with pendula, harmonic motion, and the wave equation. Of all of this, figuring torque out was the hardest of all. I understand why its vector points in or out of the page (z axis) mathematically as a cross-product, but is this arrow simply symbolic of the spin-direction, or is it something more than simply a way of telling spin. As in, can there be any reflection of this defined vector more directly. I also understand torque is too a tensor, so I accept that may be relevant to my question.
