They have streamlined bodies so that they can cut through the wind and air
Streamlined shapes make them faster and more fuel-efficient.
to fly
The body of ships and boats are streamlined coz that they can experince minimum amount of Friction while moving through water
Aeroplanes are built streamlined to increase their flight efficiency. A number of other reasons are involved, but this is the main reason.
Yes , example of streamlined .
Aeroplanes and Ships
Aeroplanes and cars have a streamlined shape because it reduces the amount of air drag / air resistance, thus allowing less amounts of energy to be wasted. For example, it cars were to be designed like trucks, this would increase friction, slowing the object down. Take the example of sports cars. They are streamlined so that when it flows through the air, the car can travel smoothly, not clumsly-like movements. Trying experimenting this with a parachute and you'll see why.
The body of ships and boats are streamlined coz that they can experince minimum amount of Friction while moving through water
Their shape and aerodynamic efficiency makes them streamlined.
To reduce friction. making the body streamlined makes the fluid friction less.
By shipping it from aeroplanes and ships.
Air rushing against an aeroplane is probably an example of a body moving through fluids. Since air is a fluid, aeroplanes moving through experiences a drag force in the opposite direction which is why the shape of faster aeroplanes are always made more streamlined.
