I was looking at this exam question, and i had trouble figuring what it means.
This question is on mechanics.
Two horizontal forces X and Y act at a point O and are at right angles to each other..
I can't seem to understand how it is possible that there can be two horizontal forces acting on a point and are at right angles to each other.
Please explain.
The question is set in 3D. Wlog one axis is vertical and the other two are horizontal.
