When we reduce the air resistance on a body, we say that the body has been streamlined. Streamliningis a concept commonly used in fluid mechanics and has been adopted by automobile industry, among others. Streamlining allows us to achieve high speeds and power. This generally refers to, in simplest terms, smooth surfaces and unbroken corners. For example, look at the surface of any car, it is very smooth and its edges and corners are...
When we reduce the air resistance on a body, we say that the body has been streamlined. Streamlining is a concept commonly used in fluid mechanics and has been adopted by automobile industry, among others. Streamlining allows us to achieve high speeds and power. This generally refers to, in simplest terms, smooth surfaces and unbroken corners. For example, look at the surface of any car, it is very smooth and its edges and corners are also smooth. In other words, the surface does not allows much scope for air resistance. This allows us to achieve high speeds, thereby reducing our travel times. Similar concepts are also used in design of trains, airplanes, ships, tall buildings, etc. A commonly used facility to check the streamlining of a body (or a small scale model) is wind tunnel.
Hope this helps.
