- A trough with a trapezoidal cross-section, as shown in the figure, contains vegetable oil with density 910 kg/m³. (Use g = 9.8 m/s² for the acceleration due to gravity.) 2m → T 3 m J 4 m Ⓡ 1 m (a) Find the hydrostatic force (in N) on one end of the trough if it is completely full of oil. 35868 XN (b) Compute the force (in N) on one end if the trough is filled to a depth of 1.5 m. (Round your answer to two decimal places.) 17431.85 XNA metal rod of length 79 cm and mass 1.44 kg has a uniform cross-sectional area of 7.6 cm2. Due to a nonuniform density, the center of mass of the rod is 28.0 cm from the right end of the rod. The rod is suspended in a horizontal position in water by ropes attached to both ends (the figure). (a) What is the tension in the rope closer to the center of mass? (b) What is the tension in the rope farther from the center of mass? (Hint: The buoyancy force on the rod effectively acts at the rod's center.)The L-shaped tank shown in the figure is filled with water and is open at the top. If d = 5.35 m, what is the total force exerted by the water (a) on face A and (b) on face B? 3d (a) Number (b) Number d d 2d i d 2d d B Units Units <
- A dam on a river is built so that the wall facing the water is shaped like the region above the curve y = 0.3x² and below the line y 100. All distances are measured in meters. The water level is 25m below the top of the dam. The gravitational acceleration is g = 9.8m/s² and the density of water is p= 1000kg/m³. Find the hydrostatic force exerted on the dam. Answer (in Newtons):Consider the rectangle with length a = 1.8 m and width b= 1.5 m, located d=0.7 m below the water surface. Determine the resultant force P due to the water acting on the rectangle. P= Round your answer to 2 decimal places. kN ho= Round your answer to 2 decimal places. mOn a distant planet, where the gravitational field strength is 10.0 N/kg, a block of mass 20 kg hangs from the end of a 5-m fishing boon of mass 14 kg. A cable is attached to the boon two meters from the pivot at an angle of 53º. The submerged block has a mass of 20 kg, but the tension in the rope supporting it is only 140 N (because of the buoyant force). T₂ = T₂=? 53⁰ (a) The tension, T2, in the cable is: Volblock 5 m water mmmmmmmm 3 m N (± 5N) T₁= 140 N 2309 (b) What is the volume of the block? Remember, the density of water is 1 g/cc. cm³ (± 5 cm³) kg
- (5) Logs sometimes float vertically in a lake because one end has become water-logged and denser than the other. What is the average density (in kg/m3 ) of a uniform-diameter log that floats with 30.0% of its length above water?A vat contains a mixture of oil and water. The water forms a lower layer which is 0.8 m deep, and above it there is an oil layer 0.3 m thick. The density of water is 1000 kg/m3, and the density of oil is 800 kg/m3. Find the force on a flat door at the bottom of the vessel that has a cross-sectional area of 0.5 m2. The acceleration due to gravity is 9.81 m/s2.An Airbus A380-800 passanger airplane is cruising at constant altitude on a straight line with a constant speed.
