How can you appreciate the technology of making ships float, using the material which sink in water?

Answer»
  • We know that a piece of iron sinks in water. 
  • The relative density of iron is 8.5 which is many times more than water. 
  • A ship that floats on water is made up of tonnes of iron. It is really wonderful. 
  • According to the Archimedes principle of buoyancy, any object can float when its weight is equal to the weight of water displaced by it. 
  • Hence ships are made with a larger surface area so that it displaces the water, whose weight is equal to the weight of loaded ship.
  • It involves very sharp scientific calculations and a large engineering technology. 
  • Really such type of technologies are highly appreciable and the scientists who formulates all these are also really great.
