QUESTION Determine the following for the curved surface BC and as shown in figure I. Centroid of the curved surface 2. Horizontal hydrostatic force 3. Vertical component of hydrostatic force 3m Realtant of tydrsttic force and its poaition or Total Pressure Moment of vertical hydrostatic force component about the plane C Moment of horizontal hydrostatic forces. 5. 60 6. TITRII 82.

SOLUTION I. Centroid of the curved surface curved surface B H-3m 1Bc BC C.

SOLUTION 2. Horizontal force on BC BC BC P- X 1x2 unit dth 8OKN methe width

SOLUTION 3. Vertical component of hydrostatic force tv suppmted e cuved R 4

SOLUTION 4. Resultant force on curved surface 802 41.422 FH

SOLUTION Ah 5 and 6. Moment of hydrostatic forces (BC) H-3m BC 77.572 kNm Gi P. (F )c 8C (3+2) 408 = 73.6 kNm
