Why the design of car and submarine is of oblong shape?

The oblong shape of cars and submarines is primarily for aerodynamic and hydrodynamic efficiency. In cars, the streamlined shape reduces air resistance, improving fuel efficiency and overall performance. In submarines, the oblong shape allows for smoother movement through water, reducing drag and making it easier to control the vessel at varying depths. Additionally, the oblong shape provides more internal volume for passengers, cargo, and equipment while maintaining stability in motion.


Which shapes are the most aerodynamics?

What defines a shape as being aerodynamic is that is has as little resistance as possible at the front of the shape (whichever direction is moving forward) and also allows the air to rejoin after the shape with as little turbulence as possible. So the most aerodynamic shape would be a needle that is pointed at both ends. However this shape is not really useful in most applications, but the idea of this pointed at both ends shape can be seen in many of the newer cars. Look at a prius for example, the front is pointy and the back is designed as a point but is cutoff prematurely.


What are the Characteristics of useful information?

There are many characteristics that can be seen of useful information. Useful information is something that is helpful or relevant.

Do the fluid friction is minimum for objects that have a streamlined shape?

Yes, objects with a streamlined shape experience less fluid friction compared to objects with a less aerodynamic shape. The streamlined shape helps in reducing drag by allowing the fluid to flow smoothly around the object, thereby minimizing resistance.
