The coordinate system Oxy is defined above. First, we find the x and y components of vector F 2 and F 1 F 1 ,x 200 cos 45 0 141.42 lb F 1 ,y 200 sin 45 0 141.42 lb F 2 ,x 150 cos 60 0 75 lb F 2 ,y 150 sin 60 0 129.9 lb Computing the resultant vector’s x and y components by adding x components and adding y components of F 2 and F 1 . The resultant vector is denoted F. F x F 1 ,x F 2 ,x 141.42 75 216.42 lb F y F 1 ,y F
