So at joints C and D do I let there be a Cx, Cy and Dx, Dy respectively or do I just keep it as Fwd and Fwc? Either way I can't seem to solve it. â‘Fx=0=WD-4293cos19.74 ÎŁFy=0=Fwc Sin19.74 - 1450 Fwc= 4203 lb WD = 4041 lb Then at joint C â‘Fx=0=CDsin30 - CAsin30 - 4041 â‘Fy=0=1450-CDcos30-CAcos30 CD = 4878 CA = -3204 Incorrect.
