A 400.0-N sign hangs from the end of a uniform strut. The strut is 4.0 m long and weighs 600.0 N. The strut is supported by a hinge at the wall and by a cable whose other end is tied to the wall at a point 3.0 m above the left end of the strut. Find the tension in the supporting cable and the force of the hinge on the strut.
When the structure shown below is supported at point P , it is in equilibrium. Find the magnitude of force F and the force applied at P . The weight of the structure is negligible.

if C is the vector sum of A and B, C=A+B, what must be true about the direction and magnitudes of A and B if C=A+B? what must be true about the direction and magnitudes of A and B if C=0?
For the second question either |A| and |B|= 0 or |A|=-|B|, If |A|= -|B| and |A|>0, then Phi[A,B]=180 Degree or π rad
Allthese
For the first question let |A| and |B| >O, then it is possible that |C|< |A| and |C|<|B| if Phi [A,B]<90 degree= |A| and |C|>|B|
Allthese
A correction to the first question If Phi[A,B] is within 90-270 degrees, then |C|> |A| and |C|>|B| define Phi[A,B] ≡ X, If 90 degree  ≤ X ≤ 270 degree (Phi[A,B] defined as X is within 90 to 270 degree including 90 degree and 270 degree) Then |C|> |A| and |C|> |B|
