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. 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??
