A light triangular plate OAB is in a horizontal plane. Three forces, F1=4N, F2=12N, and F3=4N, act on the plate, which is pivoted about a vertical axis through point O. Find the torque (or "moment") of force F1 about the axis through point O.

Re: Statics Problem...
You can use trig to get d.
Sometimes it is easier to split F1 into a horizontal component (F1cos30) and a vertical component (F1sin30) and then get the moment of each.
As the vertical component acts through O it will have zero moment.
If you do it this way you'll get the same answer so it would be worth trying both just for the practice.
