A 2-m-high, 3-m-wide rectangular gate is hinged at the top edge at A and is restrained by a fixed ridge at B. The container is filled with 5-m-high Engine oil SAE 10W-30 (SG=0.875) a) Determine the hydrostatic force exerted on the gate b) Determine the location of the center of pressure c) Describe the force exerted by the oil on the gate d) What does the center of pressure mean? And why is it always located below the centroid of the submerged surfaces? e) Draw a sketch showing the location of the centroid and the center of pressure V 1 m SAE 10W-30 A 2 m Gate B
