1. The problem statement, all variables and given/known data http://imageshack.us/a/img5/629/meprob25.jpg [Broken] A. Determine magnitude of resultant force (of F1 and F2 acting on the point) B. Resolve F1 in to components along the u and V axes and determine the magnitudes of these components. C. Resolve F1 in to components along the u and V axes and determine the magnitudes of these components. 2. Relevant equations law of sines, Pythagorean theorem 3. The attempt at a solution I just need help with parts B and C. A goes : Fx = 150(cos60) + 200(cos45)= 216 lb Fy = 150(sin60) + 200(sin45) = -11.5 lb (2162 + 11.52)1/2 means R = 216 lb at 3 deg under the U axis because tan-1(-11.5/216) = -3 For part B the only guide to find how to solve these before is use law of sines, but trying to solve for resolving the components of F1 along a and B: 200 / (sin45) = F(u) / 1 F(u) = 282 lb but it is supposedly wrong. Any hints?
