# Net Torque calculation

Calculate the net torque about point O for the two forces applied as in the figure View Figure . The rod and both forces are in the plane of the page. Take positive torques to be counterclockwise.

A image is here to show the problem

What i did
12Nsin(30)*(2m)-(8N*3m)
or if you like this better
F2sin(theta)*d-(F1*d)
however this isnt working should i not be neglecting the y component of F2 or do i have the angle wrong....i am confused any help is appreciated.

it appears my image is taking forever to get approval so i will try and explain the problem.
there is a rod where the axis of rotation is on the left end of it
2 meters from this axis is a force going up and to the left, at a 30 degree angle. with a magnitude of 12N (F2)
Another force is a total of 5 meters from the point of rotation and is vertical with a magnitude of 8N (F1)
nevermind i turned out to be right...i just made a dumb error.

i'm confused as to how to come up with an answer, trajan22. did you happen to get -12 ..clockwise for the answer??
