    Support Vectors
AI Thread Summary
The discussion confirms that the reaction vectors presented are mostly correct, assuming mu equals zero. However, there is a suggestion to reverse the direction of the horizontal vector, as it may be drawn backwards. If this vector is indeed backwards, its numeric result will reflect a negative sign. The participant expresses uncertainty about their understanding of the vectors involved. Overall, the feedback provides clarity on the correctness of the vectors while highlighting a potential error in direction.

Are my reaction vectors correct?

Truth be told I'm not exactly sure what am I looking it... but did I get it right?

Dory: Yes, nice work. Your reaction vectors look correct (if mu = 0). However, it currently looks like your horizontal vector might be drawn backwards. Therefore, you might want to reverse its direction. If it is drawn backwards, then the numeric result for that vector will have a negative sign, telling you the direction of that vector is drawn backwards.

Ah, good, thanks... wasn't sure about the one in the middle. Still no idea what I'm looking at, heh.
