Maritime transportation: simple drawing pictures of ships
Modern ships refer to ships driven by mechanical engines and are mostly made of steel. Primitive steamships were propelled by human power on wooden wheels. Modern ships are steamships that use steam to push external paddle wheels. Modern ships mostly use turbine engines. A ship that does not use sails but uses a steam turbine for forward propulsion is called a steam ship. The fuel used by steamships is coal. There is a big wheel outside the steamship, so it is also called a "steamship". It was invented by Fulton. Ships are generally used in both a narrow sense and a broad sense. The development of ship propulsion has gone through two methods, one is the primitive propulsion with human stepping on wooden wheels, and the other is the modern propulsion with mechanized propellers. Narrow definition of ship. A ship in a narrow sense refers to a ship propelled by a steam turbine. In 1807, American Robert Fulton built the worlds first steam-powered ship. Here, the ship becomes a machine that replaces intermittent motion with continuous motion.
