Scientific Enlightenment:

A amphibious vehicle is a special vehicle that possesses both the characteristics of a car and a boat. It can both drive on land and float on water. Due to the amphibious vehicle's outstanding performance in both land and water travel, it can cross rivers, lakes, and oceans while driving, without being restricted by bridges or boats. Therefore, it has received wide attention and application in transportation, especially in military applications.
The development of amphibious vehicles can be traced back hundreds of years. The earliest recorded amphibious vehicle was invented by Americans in 1805, which was accurately described as "a steam-powered vehicle with wheels that can also sail." From the structure and usage, this invention was indeed a vehicle that could travel on land but also sail on water. In recent years, the research and development of civilian amphibious cars has progressed rapidly, with inventors from various countries designing various styles of amphibious vehicles. For example, a company in England has successfully developed an amphibious car that can reach a top speed of 100 miles per hour on land and 30 miles per hour on water. It is said that the company plans to produce 100 of these cars. It was not until the military field that amphibious vehicles were truly applied and mass-produced. One of the more famous amphibious vehicles is the German Army's Volkswagen 166 amphibious vehicle during World War II. It could reach a top speed of nearly 90 kilometers per hour on land and about 10 kilometers per hour in water. After being equipped to the troops, it was widely welcomed by the German soldiers and officers. By the end of 1944, a total of 14,238 vehicles had been produced at the Wolfsburg factory and the Porsche factory in Stuttgart.

Scientific Principles:

A amphibious vehicle is based on Archimedes' famous law that the amount of buoyancy an object experiences in water is equal to the weight of the water it displaces, which is equal to the specific gravity of the water times the volume of the object's submerged portion. Tank and armored vehicles also rely on sealed bodies to obtain a certain amount of buoyancy, similar to submarines. Since the body is relatively small and not as large as a submarine, the weight cannot be too great, or it will be difficult to ensure positive buoyancy. The armor of general amphibious armored vehicles is generally thinner, and there is usually an additional body float box. With the addition of sealing, drainage systems, and propulsion systems (track sliding, spray nozzles, propellers), tanks can navigate on water.
