- QUESTION 1A solid cylinder is to be 0.25 m in diameter. The base of axial length 25 mm is to be of metal which has a specific gravity of 7, and the remainder of material which has a specific gravity of 0.5. Find the maximum overall length of the cylinder so that it may float in water in stable equilibrium with its axis vertical. QUESTION 2A square block (?? × ??) in a plan, has a height ?? and a relative density of 0.8. What would be a permissible ????limit so that the cylinder may float in stable equilibrium with its axis vertical?arrow_forward1265 mm 195 mm 825 mm 1. If the water rises to 150 mm above the bottom of the door, calculate the hydrostatic force on the door (using standard units), Why?

- Situation. A right circular cylinder having a diameter of 1.00 m and weighing 900 N is held in position by an anchor block such that 0.30 m of the cylinder is below the surface of the water with its axis vertical. The anchor block has a volume of 0.50 cubic meters and weighs 24 kN per cubic meter in air. Assume sea water to have specific gravity of 1.03. Neglecting the weight and volume of the cable. 1.

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 metal bar weighs 3.0 kg. When it is completely submerged in water as it is hanging from a portable weighing scale, the scale reads 2.46 kg. Is the metal bar made of gold? Explain your answer.

- The total pressure force of a square plate is 25 kN, placed vertically in water so that the center of the plate is 1.5 m below the free surface. Determine the size of the plate and the depth of center of pressure. The above square plate is taken out of the water which weighs 370.5 N in air and 180.3 N in water of specific gravity 0.99. Find the volume and specific gravity of the square plate. Draw a neat sketch.arrow_forwardA square plate (each side equal to 3m) is submerged vertically in water such that the upper edge of the plate is at depth 1m from the free surface.

- A vertical plate is submerged in water and has the shape as seen in the picture. Using the fact that the weight of water is 62.5 lbs/ft³, calculate the hydrostatic force (in Ibs) against the end of the tank. Give your answer correct to the nearest hundred.
