Question 1.120 marks! Gate ABCD is 4.0 m wide into the page) and is supported at B. The gate includes a quarter circle curved surface (AB) and two plain surfaces (BC and CD). The tank is open to the satmosphere from all sides and is filled by oil with specific gravity of S, = 0.9 ✓ 1- Calculate the resultant hydrostatic force on plain surface CD and find is location from the free oil surface (5 marks). 23 * 2. Calculate the resultant hydrostatic force on surface BC and find its location from point B (3.5 marks). 3. Calculate the horizontal component of resultant hydrostatic force on the curved surface AB and find its location from the free oil surface (4 marks). + Calculate the vertical component of resultant hydrostatic force on the curved surface AB and find its location from point B (3.5 marks). 5- Calculate the magnitude and angle of resultant hydrostatic force on the curve surface AB (2 marks). 2 Tao 6- Show the calculated forces magnitude (AB Vertical, AB Horizontal, BC and CD) and their location on a diagram (2 marks). x = 9.81 kN/m?) 5 FFS Gate width = 4m un A R=5m + i2m 5 R=5m 5m 5.781 X ドマー 3m Per 309.05 KN 2.61 eu BNER - 4m XX Figure 1.
