The door shown provides outdoors access to the basement of a building. The door has hinges at points B, C, and D, and it weighs 80 lb with center of gravity at point G. The force F acts perpendicular to the door.

If F = 50 lb, determine the resultant moment of F and the 80 lb weight about line BCD.
