A single small lever
because king heroin challenged Archimedes to bring a ship to the beach single handedly. so archimendes thought and thought then came up with the pully
archimedes principle
The Archimedes screw is used for irrigating crops and liftin water from mines and ship bilges.
Archimedes principle. See how much water it displaces.
Total water displaced by a ship is equal to the Weight of the ship is a live example
Its Purpose was to irrigate and lift water From mines and Ship Bilges
The weight of water displaced by the floating ship is less than the weight of the ship. So it floats. Thanks to Archimedes!
A ship's buoyancy is typically measured by calculating the weight of the water it displaces compared to the weight of the ship itself. This is known as Archimedes' principle. It can also be determined by measuring the ship's draft or submerged volume.
The upward force on a ship in water is called buoyant force. It is equal to the weight of the water displaced by the ship, according to Archimedes' principle. This buoyant force helps keep the ship afloat.
Archimedes principle led to the Plimsoll Line, which is marks painted near the bows of a ship. Basically, a ship on salt water floats higher and can carry more cargo. While a ship on fresh water will float lower and can safely carry less cargo. Samual Plimsoll introduced the Plimsoll Line to solved the hazard of capsizing posed by overloading a ship.
When vessel floats on a liquid, then it displaces a volume of that liquid, whose mass equals the mass of the vessel. If our vessel is hollow, as a ship or a bowl would be, then there is available some of the volume for the carrying of a load. Archimedes is attributed with this discovery.
A fully loaded container ship floats because of the principle of buoyancy. The weight of the ship is supported by the water it displaces, according to Archimedes' principle. As long as the weight of the ship is less than the weight of the water it displaces, the ship will float.
