\(F1=75 N; θ=0\) \(F2=50 N; θ=30\) \(F3=40 N; θ=150\) F1= \(f_1x=75cos(0)=75 N\) \(f_1y=75sin(0)=0 N\) F2= \(f_2x=50cos(30)=25\sqrt{3} N\) \(f_2y=50sin(30)=25 N\) F3= \(f_3x=40cos(150)=−20\sqrt{2}N\) \(f_3y=40sin(150)=20 N\)
Is this good so far?

I don't agree with f3x
everything else looks good
Looks good! next simply add them component by component
Ahh I didn't check the arithmetic..
this should fix it : \(F1=75 N; θ=0\) \(F2=50 N; θ=30\) \(F3=40 N; θ=150\) F1= \(f_1x=75cos(0)=75 N\) \(f_1y=75sin(0)=0 N\) F2= \(f_2x=50cos(30)=25\sqrt{3} N\) \(f_2y=50sin(30)=25 N\) F3= \(f_3x=40cos(150)=−20\sqrt{\color{red}{3}}N\) \(f_3y=40sin(150)=20 N\)
much better
Okay. Thanks! @jim_thompson5910 and @ganeshie8 !!! I'll deal with the arithmetic, it's not the problem for me now. But the next step is what i'm having problems with.
you have the vector components, add up the corresponding components
u = v = w = u+v+w =
|dw:1440991132300:dw|
|dw:1440991352564:dw|
Okay, thanks. makes sense !
you'll end up with some vector z = p = sum of the Fx q = sum of the Fy magnitude of z = |z| = sqrt(p^2 + q^2)
what about theta?
theta = arctan(q/p)
Oh yes. I forgot about that xD
theta = arctan(q/p) if theta is in Q1 or Q4 theta = arctan(q/p)+180 if theta is in Q2 or Q3
to figure out which quadrant theta is in, simply look at the vector
Absolutely. Alright thanks for all the help.
sure thing
