A cylinder with a diameter of D floats upright in a liquid. When the cylinder is displaced slightly along its vertical axis, it oscillates about its equilibrium potions with a frequency w. Assume that this frequency is a function of the diameter D, the mass of the cylinder m, and the specific weight y, of the liquid. 1. Using Buckingham Pi Theorem, determine how the frequency is related to these variables. 2. If the mass of the cylinder is increased, will the frequency increase or decrease?
