Q2 The helicopter deck on a ship is attached to the hull structure through rubber mountings, which provide damping for heavy landings. The effective damping ratio is 0.68 and the stiffness of the deck is 16.6 MN/m. To land in high seas the pilot hovers directly above the deck at a height h until the motion of the ship subsides. The pilot then allows the helicopter to fall freely onto the deck. This situation is illustrated in Figure Q2. (b) Working from first principles, determine the maximum displacement of the deck, and the time after the helicopter touches down at which the maximum displacement occurs. [9] C Figure Q2. k h
