Question

Calculate the components of vector Fvec1 . Calculate the cosine and sine of the angles for vectors Fvec2, Fvec3, and Fvectotal. Solve the vector equation for the magnitudes of vectors Fvec2, Fvec3, and Fvectotal .
Fvec1 + Fvec2 + Fvec3 = Fvectotal and F3 = k F2

( 68.1 N angle-80.1° ) + ( F2 angle130.6° ) + ( F3 angle140.2° ) = Ftotal angle171.9°'

F3 = 0.42 F2

Fvec = F angle? Fx = F cos? Fy = F sin?
Fvec1 = 68.1 angle-80.1° (11.71)N (-67.09)N
Fvec2 = F2 angle130.6° (-.6508)F2 (.7593)F2
Fvec3 = F3 angle140.2° (-.7683)F3 (.6401)F3
Fvectotal = Ftotal angle171.9°Fvectotal (-.9900) Fvectotal(.1409)

SFx = (11.71 N ) + ( -.6508) F2 + (-.7683) F3 = Ftotal (-.9900)
SFy = ( -67.09N) + (.7593) F2 + (.6401) F3 = Ftotal (.1409)
F3 = 0.42 F2

Fvec2 = (__)N angle130.6° HOW TO GET THIS ANSWERS???

Fvec3 = (__) N angle140.2° HOW TO GET THIS ANSWERS???

Explanation / Answer

   as given in the problem,F3=0.42F2       net force along x-axis, SFx = 11.71N -0.6508F2-0.7683F3 = 11.71N - 0.97F2                                        SFx = -67.09N +0.7593F2+0.6401F3 = -67.09N +1.03F2    again as given in the problem,                                                                              SFx = 11.71N - 0.97F2 = Ftotal(-0.9900)                                          SFy = -67.09N +1.03F2 = Ftotal(0.1409)                    It is impossible to solve, unless you give the value of Ftotal    again as given in the problem,                                                                              SFx = 11.71N - 0.97F2 = Ftotal(-0.9900)                                          SFy = -67.09N +1.03F2 = Ftotal(0.1409)                    It is impossible to solve, unless you give the value of Ftotal
