Question: 1 Along, solid cylinder of radius 2 hinged at point is used as an automatic gate, as shown in Fig. When the water level teaches 15 the cylindrical gate opens by turning about the hinge at point A. Determine the hydrostatic force acting on the cylinder (Answer 1747 IO 15 Lo Question 12 Considera bany car ubmerged in water is lake with a fie bottom. The driver's side der of the car as Ilm high and 9 m wide, and the top edge of the descris 8 m below the water surface Determine the set force acting on the doce normal to its surface and the location of the pressure centre if the car is well-scaled and it contains test atmospheric pressure (Answer 83 KN and th) The car is filled with water Questi Consider a 4-m-lenty 4-in-wide, tad 15-m-high aboveground swimming pool that is filled with water to the im a) Desemine the hydrostatic force on each wall and the distance of the line of action of this fonce from the ground If she height of the walls of the poed in divabled and the pool is filled will the hydrostatic fiece on each wall double or quadruple? Why? Question The flow of water from a reservoir is controlled by a sf-wide shaped gane hinged at point as shown in Fig. If it a desired that the gate open when the water height is determine the mass of the required weight (Awwer 1400 ) 81 | 8
