Problem *3.112 [Difficulty: 2] Given: Steel balls resting in floating plastic shell in a bucket of water Find: What happens to water level when balls are dropped in water Solution: Basic equation F B ρ V disp g = W = for a floating body weight W When the balls are in the plastic shell, the shell and balls displace a volume of water equal to their own weight - a large volume because the balls are dense. When the balls are removed from the shell and dropped in the water, the shell now displaces only a small volume of water, and the balls sink, displacing only their own volume. Hence the difference in displaced water before and after moving the balls is the difference between the volume of water that is equal to the weight of the balls, and the volume of the
