Determine the design angle 
for connecting member A to the plate if the resultant force is to be directed vercially upward. Also, what is the magnitude of the resultant?
R = 400 N, = 53.5°
= 53.5°R = 250 N, = 30.0°
= 30.0°R = 300 N, = 36.9°
= 36.9°R = 640 N, = 38.6°
= 38.6°Discussion:

To get net force only in y direction, net force in x direction must be zero. Therefore there should be 400N force in negative x direction. This force will be the component of 500N force in negative x direction.
Hence 500cos(theta) = 400.
cos(theta) = 400/500 = 4/5.
Theta = 36.9 degree.
Hence 500cos(theta) = 400.
cos(theta) = 400/500 = 4/5.
Theta = 36.9 degree.
