I've been trying to figure this out for 4 days now. I'm completely stumped. I've attached a picture of the diagram: http://postimage.org/image/t3d5i0l1v/ I found the force in F: F = 25.04 lb ---> 16.92i + 18.46j Now I need to find the support forces at A and B. I'm not sure if this is right but I came up with the following equations: I used the angle at the supports as 42°. ƩFx=0= -Bx*cos42 - Ax*cos42 +16.92 ƩFy=0= - By*sin42 - Ay*sin42 +18.46 Then I thought about taking the moment about point A: ƩMa=0=Fx*2 + Fy*9 - Bx*cos42 *(9) - Bysin42 *(8) Then the moment about the other points F and B. A the end I got the following equations. ƩFx (Eq. 1): (0.743)Ax + (0.743)Bx = 16.9 ƩFy (Eq. 2): (0.670)Ay + (0.743)By = 18.5 ƩMa (Eq. 3): (6.7)Bx + (5.63)By = -200 ƩMb (Eq. 4): (6.7)Ax - (5.63)Ay = 100 Now when I try to solve these equations my unknowns cancel out!! What’s the deal!!!!!??
