The supporting structure of the billboard is attached to the ground by a pin at B, and a roller at A. Point G is the center of gravity of the billboard and structure, which together has a weight of 1400 N. To prevent tipping over in high winds, a 1200-kg mass is placed on the structure near A, as shown. Compute the magnitudes of the reactions at A and B if the wind load on the billboard is q = 1200 N/m.
