Question

Wgat is the streamlined body

Answer 1

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. Drag is a force that slows down motion; friction drag is a special kind of drag. 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.

Answer 2

it is the shape in which path of a fluid flowing steadily and without appreciable turbulence. A body is said to bestreamlined if its shape offers the least possible resistance to a current of air, water, or other fluid.

streamlined body of a fish is long and thin and pointed at both ends. This is called astreamlined shape. A streamlined shape moves faster through water than other shapes. This is because it can cut through the water more efficiently than other shapes.

When objects move, the air around them generates a type offriction called air resistance, or drag, that slows them down. Fast-moving objects such as cars, trains, and aeroplanes are all streamlined – designed with curved and sloping surfaces to cut through the air and reduce drag.
