Extracted text: Problem 7: A brass weight is to be attached to the bottom of the cylinder made from a uniform material with specific weight 6.46 kN/m³, so that the cylinder will be completely submerged and neutrally buoyant in water at 95°C which has density of 9.44 kN/m³. The brass is to be a cylinder with the same diameter as the original cylinder as shown in the figure. What is the required thickness of the brass? Water surface Cylinder Water at 95°C 750 mm Brass plate Y=84.0 kN/m 1= ? 450 mm diameter-
