How could you use a wrench to explain why a x b = - (b x a) for any vectors a and b?
I really dont understand how to convey this in word , thanks for any help !
imagine a wrench being used to tighten and/or loosen a screw. you can use the right hand rule to see how a x b differs depending on whether you are tightening or loosening the screw. one vector will be in the direction coming out of the screw head, perpendicular to the wrench, the other will go the opposite way, from the threading pointing into the hole.
