Hey Professor at 4:59. Apply the geometry rule angles inside a paralellogram = 360. Inside the parallelogram (lower corner & top corner) = 105.1° and thus 2(105.1°) + 2(X°) = 360. Angle X = 74.9°. Right? So, that angle 74.9° is the angle opposite of Fr. Now use the law of cosines. Done. Now, use that same method at 11:52. 2(10.63°) + 2(gamma) = 360 → gamma = 169.37 degrees. Done. It took you a minute and a half to get that.
At 6:35 u showed fY value as direction to resultant but we should add value to fY to get direction with respect to horizontal I mean after finding final Fr value for angle we should add either 55 or 19.9 so that we get wrt horizontal
Thanks man, you're the best
Great energy as always!

Nice teaching
You're the most pog guy ever :D
what is the white digital board that you are using ??
what software do you use to write these problems out? thanks
I use onenote
FIRST to comment. 😄
Hahaha
