When objects move, the air around them generates a type of friction called air resistance, or drag, that slows them down. This helps them to move faster and use less fuel. Streamline is slimmer at the ends and thicker at the middle. It helps to decrease the drag created by fluids and thus allowing the body to move freely. The shape of the boat is streamlined and this shape helps in reducing friction.
The boat will speed easily through the waves. 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. A streamlined process means fewer errors and delays. You probably use dozens of business processes every day. For example, you may go through the same steps each time you generate a report, resolve a customer complaint, contact a new client, or manufacture a new product.
Answer: Streamlining is a design that offers the least resistance to the flow of a fluid, especially air or water. Friction is minimum for a streamlined shape, which is rounded in the front and narrow at the back. It is useful as: Ship also have streamlined shapes to reduce friction with water. Answer: The four examples of streamlined objects are a car,an airplane,a rocket,a bullet,a ship,a submarine,a dolphin.
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. The special shape given to the bodies moving in the fluids like ships in water and aeroplanes in the air to reduce the fluid friction is called streamlined shape. The car design top-right resembles a people-carrier or transit-van, using a sloping front to minimise wind-resistance while generating the required down-force.
Interestingly, it was evolved around the chassis of a common saloon car, but the computer preferred this type of design solution. The first boat hull bottom-left resembles that of a traditional small boat or ship, with a pointed and sloping bow to direct 'water' to either side of the hull and to generate the desired up-force.
The second evolved hull bottom-right resembles a twin-hulled catamaran, directing water underneath the hull to allow it to cut through water cleanly and generate the desired up-force. All of these were each once the height of technology.
But today are normally only used for sport and pleasure craft. Modern ships normally use some variation of a propeller due to the higher efficiency and performance. For the ship to move, the propeller needs a source of power, or a engine.
This is normally placed in the centre of the ship low down as it can be very heavy. To connect the engine to the propeller, a propeller shaft can be used, providing a physical link. Get the series on your phone or tablet and listen whenever you like — at home, in the car or onboard your very own ship! But if the front of the boat is flat, like on a barge, the water friction will slow it down.
The water will push against the boat. The boat won't be able to go quickly. 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.
