Calculating the moment of force F about the axis isn't hard; how do I determine how to produce the maximum moment?
Maxis = ûaxis ⋅ (r×F)
F = 30N (This doesn't change at all during the problem)
The Attempt at a Solution
I would guess that since the problem axis is parallel to the y-axis, you should minimize that component of the force (β=90°). I'm not totally sure on that point though. As for the other two axes, I have no idea.
