right cylindrical object has a diameter of 1526 mm and a height of 2.1m. The density of water is 1000 kg/m3. If the right cylindrical object is placed in the water, what is the buoyant force?
A cylindrical object 85mm diameter, 157mm height and a mass of 601g, is placed in the tank, which contains oil(51mm thick) and water. Calculate the height(in mm) above the surface of the oil at which it will float if maintained in the vertical position. Take density of oil equals 966 kg/m³. Answer in two decimal places. Numerical values only. Don't indicate units here, just on the submitted solution.
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.
The following questions consider the stability of a floating iceberg. Approximate the iceberg as a perfect cylinder of uniform density, If the iceberg has a diameter of 3 meters and a length of 0.5 meters find the location of the metacenter as measured from the bottom of the iceberg. Take the density of sea water to be 1030 kg/m3 and the density of the ice to be 920 kg/m3.

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. (Hint: First set up a Riemann sum that approximates the hydrostatic force, which can then be used to obtain an integral that represents the force.) 12 ft 8 ft 20 ft Hydrostatic force = Ibs
