The three forces acting on the water tank represent the effect of the wind. Replace this system by a single resultant force and specify its vertical location from point O.

• A. R = 600 lb, d = 65.0 ft below O
• B. R = 600 lb, d = 130.4 ft below O
• C. R = 600 lb, d = 65.0 ft above O
• D. R = 600 lb, d = 130.4 ft above O
