Question

What do you mean by streamlined shape? How is it useful? ​

Answer 1

Answer:

A streamlined body is a shape that lowers the friction drag between a fluid, like air and water, and an object moving through that fluid. 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.

Usefulness:

Streamlining your body reduces the friction of movement to a minimum thus decreasing overall drag. For fishes having a streamlined body that is smooth helps save energy it would otherwise have to expend swimming.

WHAT IS A STREAMLINED SHAPE??

YOUR ANSWER IS HERE

A body shape which offers very little resistance to the flow of air or water around. It is known as streamlined shape. streamlined shapes look a bit like the cartoon drawing of the drops of water () although longer and skinnier.
