My question follows off of the picture attached. I have been able to answer both questions, but I still have questions of my own. I had to solve them geometrically using the Law of Cosines and the Law of Sines...why is it that I am not able to break it into components using the trig functions? Surely it has something to do with the axes not being perpendicular..but what exactly? As far as the u axis goes...it's just a direction, independent of v, so I don't understand why I cannot solve it using trig functions multiplied by the magnitude. The answer for the second problem, is about 205 N via the Law of Sines: Fx = (300*sin(40))/sin(110) Why can't I simply do cos(30)*300 ? And when I try to implement a normal perpendicular system, I still get the wrong components. What am I doing wrong? And how would you solve this analytically with trig functions and not geometrically? Thank you so much guys.
