👉 In the context of mechanical engineering, a watertight structure is one that can withstand water pressure without leakage or damage. This means it should be able to hold its integrity and prevent any leakage or damage in the event of a sudden change in water pressure or other factors. A watertight structure is typically characterized by having a tight seal between the walls and the interior space, as well as a high level of moisture resistance. The design of a watertight structure should minimize the amount of water
