why do we shape airplanes like that of a bird?
Answers
Answer:
Aeroplanes have been designed as birds. Birds have a light body, shaped such as to have a minimum wind resistance when they fly to overcome the friction. Thus, aeroplanes have been designed such as to have a streamlined body to overcome the frictional force of air.

Explanation:
It occurs when the fluid closest to the object sticks to its surface, exerting a force that opposes the object's motion. Many animals, such as birds and dolphins, and many machines, such as airplanes and submarines, have streamlined bodies to reduce friction drag as they move through either air or water.
Airplanes have wings, just like birds. They also have a light skeleton (or framework) to decrease their weight, and they have a streamlined shape to decrease drag. ... Airplane wings are designed to create lift by changing the pressure, rather than by flapping them up and down.
