So yeah, I understand that you can calculate torque as F*d, and you get a "number".(adsbygoogle = window.adsbygoogle || []).push({});

But when you calculate a cross product of torque, r x F, what does that actually give you? It is a vector, perpendicular to F and r, but what "is" that? I mean, is it like an axis around which the object is rotating? And why does it have a magnitude, does it matter ever?
