If it helps I figured it out, you have to do F1cos20 to find the hypotenuse of the triangle on the xy plane then you multiply that value by sin40 to find Fx
thats wrong calculation you took f1 cos20 then took its component in x direction right but you missed about f1 sin20 then its component in x direction you are doing wrong
You fooled me with the "non-left hand" coordinate system. Will have to check that from now on, I can never assume this again. It's okay for vector addition, but if this involved moments and cross products it would not work, of course.
Haha. Yes, you are correct. This is just for basic addition; specifically for vector components. Moments would be all messed up, if axes are not set up correctly.

I think there's an error with the summation of x forces: -60.4 + 77.1 =/= 11.6
16.7?
yep
@@Gotham_Bot yes
Excellent
I don’t understand, why f1 cos 20 x sin 40?
Did you ever figure out why😭

you are going too fast im too dumb for that fast teaching 😢😭
🤣🤣🤣🤣🤣
Play on x0.5 speed
Using Rx = 16.7 lbs:
Magnitude of vector R: 93.77 lbs
AB = 73.9 lbs
theta = 13.06 degrees
phi = 37.98 degrees
Coordinate DIrectional Angles:
alpha = 79.74 degrees
beta = 39.84 degrees
omega = 127.98 degrees
Bro thinks he knows sum 😂😂😂
Bro, Rx is 16.7 I guess? haha maybe I am wrong
