1 A structure supporting sea-water (specific gravity = 1.1) has a circular-gate in its inclined-wall as shown in the Figure 1. The gate has a diameter of 4 m and hinged at a location, O. Neglecting atmospheric pressure determine the yc, the magnitude of resultant force and yp (in meter, accurate up to three decimal places). (Given that g = 9.81 m/s²) Take last 4 digits of your student ID as a distance (m) from the water surface to the CG of the plate (see Figure-1). (For Example: If your Student ID is 218360568, last 4 digit = 0568, X=568 m) Xm HINGE CG O STOPPER 60⁰ 4m Do not scale. Yc ур
