Motion of a Buoy A cylindrical buoy with diameter 1 8 in. floats in water with its axis vertical, as shown in Fig. 4.1.14. When depressed slightly and released, its

period of vibration is found to be 2.7 sec. Find the weight of the cylinder. Archimedes' Principle says that an object submerged in water is buoyed up by a force equal to the weight of the water displaced, where weight is the product of volume and density. The density of water is 62.5 lb/ft3?
