I have a question... how can you determine the direction of Mo (clockwise or counter clockwise) from the computation of x and y?

I have encountered similar problems like that, but i get confused in determining the direction. Sometimes i get negative Mo but the direction is +clockwise, and just like this example the Mo is negative but its direction is counterclockwise..

Ps. Thanks for the solution..
