Chapter 9, Problem 110P

One side of the container has a 03-m square door that is hinged at its top edge. If the container is filled with water, determine the smallest force F that must be applied to the bottom edge of the door to keep it closed.

A spherical buoy has a diameter of 1m and floats half submerged in sea water. Determine the mass of the buoy. A piece of material density 5670 kg/m3 is now suspended beneath the buoy causing it to be just submerged. Determine the mass of material used. Ans: mass of buoy: 268.3kg, mass of materlal: 327.5

The water storage tank has a round opening 0.5 meters in diameter, which is covered by a round plate that prevents the water from escaping. The brace is anchored to the container by means of four screws that are at equal intervals from each other on a circle with a diameter of 0.64 meters, as shown in Figure 3. Given that the center of the opening is located at a depth of 1.4 meters from the water, as shown in Figure.3 The weight per unit volume of water is given and equal to y. Note that the water pressure only acts on a part of the brace which covers the opening A. The equivalent force and the position of its action on the window (center of pressure) must be determined. B. Draw (free body diagram) for the plate. C. The force must be found in each of the screws, as a result of the action of the water pressure

determine the center of pressure in m of an isosceles triangle plate of base 5 m and altitude 5 m when the plate is immersed vertically in an oil (s=0.8). The base of the plate is 1 m below the free water surface.

Determine the weight of the 45 kg square box of side 500mm. When it is submerged into the mercury?

Determine the total force in kN on an isosceles triangular plate of base 5 m and altitude 5 m when the plate is immersed vertically in an oil (s-0.80). The base of the plate is 1 m below the free water surface.

If the force acting on the circular window is 12.0 KN and its center of pressure is located 450-mm diameter 50 mm below the centroid of the window, sg-0.60 0AS m what amount of gas pressure (in KPa) is present inside the container? 15 m Circular view sg = 0.85 port is cecaterod in inelined side of tank. 030 m

Determine the smallest thickness (b) of the water gravity dam that will prevent it from tipping over due to the load from the water reservoir. The density of the concrete is 2.4 Mg/^3. The width of the dam is 1-m.

A brass weight is to be attached to the bottom of a cylinder so that the cylinder will be completely submerged and neutrally buoyant in water at 95 degrees Celcius. The cylinder has a length of 786mm .The brass is to be a cylinder with the same diameter as the original cylinder. Given that the specific weight of the cylinder is 6.52KN/m3 and that of the brass is 87.99KN/m3 . What is the required thickness of the brass? NB specific weight of water at 95 degrees Celcius is 9.44KN/m3. GIVE YOU FINAL ANSWER IN mm
