(Force on curved surface) A gate in the form of a partial cylindrical surface (called a Tainter gate) holds back water on top of a dam as shown in the figure below. The radius of the surface is 23 ft, and its length is 33 ft. The gate can pivot about point A, and the pivot point is 10 ft above the seat, C. Determine the magnitude of the resultant water force on the gate. Tainter gate 10 ft Water FG i Dam lb
