1. The problem statement, all variables and given/known data http://img687.imageshack.us/img687/8767/meprob27.jpg [Broken] If the resultant force acts along the positive u axis, determine the resultant force and angle theta (red angle) 2. Relevant equations law of sines pythagorean theorem, etc trig parallelogram, head to tail methods, something probably missing, etc 3. The attempt at a solution The resultant force comes from the 3 kN and 2 kN forces. I try -30 deg = tan-1(Fy / Fx) Fy = (2 kN)(sin θ) Fx = (3 kN) + (2 kN)(cos θ) and I get stuck here, trying to go by just what I thought was usual trig / force vectors If I have to draw another triangle to help solve, then I am not sure how. Thank you.
