A container with two circular vertical tubes of diameters d1 = 39.5 mm and d2 = 12.7 mm is partially filled with mercury. The equilibrium level of the liquid is shown in the left diagram. A cylindrical object made from solid brass is placed in the larger tube so that is floats, as shown in the right diagram. The object is D= 37.5 mm in diameter and H = 76.2 mm high. 1. Calculate the pressure at the lower surface needed to float the object. 2. Determine the new equilibrium level, h, of the mercury with the brass cylinder in place.
