The force F has a moment equal to 250N.m with respect to point O -400N.m with respect to point B and has a zero moment with respect to point A.(adsbygoogle = window.adsbygoogle || []).push({});

Find the magnitude of F and the x-intercept.

OK, here's what I did,

Using the formula for moment I got the force F*sub*B

M=Fd

-400N.m=F(2.4m)

F=-166.67 N

I think this is the y-component... right??

anyways, I got F*sub*A as zero...

Now, I can't figure out a way to utilize the moment in O and as well as get the intercept and the force....

can anyone help me??
