Which is a streamlined object example?
Which is a streamlined object example?
Answer: Streamlined objects would include objects that are designed to travel quickly and create a minimum of friction against either air or water. Some objects that are streamlined include trains, airplanes, space shuttles, rockets, boats, submarines, racing cars, racing boats, and even televisions.
What are streamlined objects?
(a) A streamlined body is the one which is pointed at the ends and broad at the middle. It helps to lower the friction drag between a fluid, like air and water, and an object moving through that fluid. Car and aeroplane usually have a streamlined shape.
What is streamlined shape give four examples?
Answer: A special shape of the bodies which reduces the fluid friction is called as the streamlined shape. Example: Aquatic animals like fish, crocodile and sharks and the vehicles like cars, flights, ships ect. Streamlined shapes help reduce the amount of air drag when an object is moving.
What has streamlined shape?
Streamlined shape means they are narrow in front and broader at the back. The bodies of aeroplanes, missiles and rockets are streamlined to reduce friction with air. Ships and boats have a streamlined shape to reduce friction with air. Nature has given birds and fish streamlined bodies.
Which is not an example for streamlined objects?
Answer : Bus is not streamlined shape.
Is boat streamlined object?
Streamlined shapes experience minimum drag (fluid friction) while travelling through air and water. Hence, boat and ships are given streamlined shape.
What animals are streamlined?
Complete Answer: – Three animals that have streamlined bodies are fishes, birds and snakes. Presence of this kind of body shape is advantageous for their living. – For fishes streamlined bodies help them swim in water with the least possible resistance.
Why is a boat streamlined?
So, with both air and water, a streamlined shape reduces friction and helps the boat or car go quickly. A flat front increases air or water friction and slows the boat or car down.
What is streamlining give examples of streamlining?
Streamline is something that has a shape that provides little resistance to air or fluid flow. An example of streamline is a slick, smooth aircraft. The path, or a section of the path, of a fluid moving past a solid object. Streamlined.
Is a cube streamlined?
The cube fell through the water the slowest. It is the least streamlined shape because it has a flat surface which will create a lot of water resistance. The water will push against the flat surface, slowing it down.
Why are boats streamlined?
Why are fish streamlined?
A: 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.
How are birds streamlined?
The bodies of all flying birds are shaped like teardrops. The streamlining is achieved by specially arranged feathers that reduce the friction that would otherwise act as a drag against the forward-moving body. TEARDROPS: The bodies of birds of all sizes share the same streamlined shape.
Why are cars streamlined?
Why do fish and boats have streamlined shape?
What is streamline in swimming?
Streamline form is a swimming technique that is used underwater in every stroke. At the start of a race or on a turn, streamline form is used, usually along with a dolphin kick or flutter kick, to create the least amount of resistance to help the swimmer propel as far as they can.
How is streamlined shape helpful for objects moving through a fluid?
Answer: Objects moving in fluids face the friction of the fluid that opposes their motion. So objects moving in fluids must have unique shapes called streamlined shapes to reduce the fluid friction.
Is a sphere streamlined?
For a given frontal area and velocity, a streamlined body will have lower resistance than a blunt body. Cylinders and spheres are taken as blunt bodies because the drag is dominated by the pressure component in the wake region at high Reynolds number.
Why do fish have streamlined body?
Fishes have streamlined body so that it can reduce friction in water and thus helping the fishes to move easily.
What are some examples of streamlined things in nature?
You can find many examples of streamlined things in nature including many different types of animals. Many animals that move through water are streamlined, including different kinds of fish, whales, stingrays, eels, and more.
How does a streamlined shape move quickly through water?
A streamlined shape moves quickly though water because it has lower friction drag against the water.
What shape does an efficiently streamlined body take?
An efficiently streamlined body thus takes on the look of a horizontally inclined teardrop shape. An aircraft or other body that is traveling at supersonicspeeds requires a different streamlined form from that of a subsonic aircraft because it is moving faster than the speed at which the pressure impulses it creates are propagatedin air.
