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
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.
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
