- A solid mat has a diameter of 3.81 cm and a relative density of 0.089. It floats in water at a depth "h". Determine this height if: al the thrust due to the air is negligible b) the thrust of the air is not negligible PAIRE=1,225kg/m° (use 4 decimal places for your calculations).arrow_forward4.0 m السرو 4.0 m The raft is made of solid square Pinewood (density= 550 kg/m'). Determine whether the raft floats in water (density = 1000 kg/m) and if so, how much of the raft is beneath the water surface. Weight of raft 0.30 m Since the density of the raft (pinewood) is less than that of water, the raft foats. Q: A force of 250 N is applied to a hydraulic piston that is 0.01 m in diameter. If the piston which supports the load has a diameter of 0.10 m, approximately how much mas can be lifted? 250 N 0.01 m 0.10 marrow_forwardA block of wood floats in water with 2 inches projecting above the water surface. When placed in glycerin of relative weight 1.26, the block floats 3 inches above the liquid. Determine the weight density of the wood.arrow_forward
- 3. A certain metal has a volume of 0.025 cu.m and when immersed in water, it weighs 500 N. Calculate the specific gravity of the object. 4. A piece of wood (sg = 0.60) 15 cm by 25 cm and 2.0 m long is floating upright in water. Determine the weight of iron, (sg = 7.8), in N, that must be fastened at the bottom of the wood such that 50 cm is above the water surface.arrow_forwardAs shown in the illustration, a 6-m-wide, 15-m-long barge is filled with rocks and floats in water. Assume that the rocks' and barge's center of gravity, G, is positioned along the centerline at the barge's surface. What is the metacentric height in meters if the barge carrying the rocks weights 1,765.8 kN? Only round off on the final answer, Use three decimal places.arrow_forwardA solid sphere has a diameter of 3.81 cm and a relative density of 0.089. It floats in water at a depth "h". determine that height ifa) buoyancy due to air is negligibleb) the thrust due to the air (1.225kg/m^3) is not negligiblearrow_forward
- A wood cube 3 cm on a side floats level on water with just 1.5 mm of the cube showing above the surface. What is the density of the wood (density of water 1 000 kg/m3)?arrow_forwardA metal block 2 ft square and 10 in. deep is floated on a body of liquid which consists of an 8-in layer of water above a layer of mercury. The block weighs 120 lb/ft3. What is the position of the bottom of the block? If a downward vertical force of 500 lb is applied to the center of this block, what is the new position of the bottom of the block ?arrow_forward1.When a double-bottom tank is full of fresh water it holds 120 tonnes.Find how many tonnes of ol of relative density 0.84 it will hold. 2. A tank measures 20 m. X 24m X 10.5 m. and contains oil of relative density 0.84.Find the mass of oll it contains when the ullage is 2.bm.
