Compute the magnitude of the resultant force (kN) on the indicated area and the location of the center of pressure (m). Show the resultant force on the area and clearly dimension its location. From the Figure shown below. 1.0 m 0.7 m Semicircular hatch 2.0 m diameter Turpentine sg = 0.88 70 %3D Question 3 (5 Marks) The Figure below shows a curved surface restraining a body of static fluid. The surface is 2.00 m long, and there is 8kPa air pressure above the fluid. Compute the magnitude of the horizontal component of the force and compute the vertical component of the force exerted by the fluid on that surface (kN). Then compute the magnitude of the resultant force (kN) and its direction (). 3.1. 3.2. Water 1.60 m 0.8 m (radius) Question 2 (5 Marks) A rectangular plane surface is 3 m wide and 6 m deep. It lies in vertical plane in water. Calculate and determine the total resultant force (kN) the position of the center of pressure (COP) on the plane surface when its upper edge is horizontal and 3.5 m below the free water surface.
