by Leta Schmitt Published 3 years ago Updated 2 years ago

Applications of Archimedes’ Principle

  1. Ships. Have you ever wondered that why an iron nail sinks in the water but large ships do not? ...
  2. Beach Balls. Beach balls are filled with air only, so they have a very small weight, hence they do not displace much water.
  3. Submarines. Submarines also work on Archimedes’ principle. ...
  4. Floating. ...
  5. Hydrometer. ...
  6. Swimming. ...
  7. Hot Air Balloon. ...
  8. Lactometer. ...
  9. Geology. ...
  10. Fish. ...

It is used in designing of ships and submarines. It is used in lactometers to determine the purity of milk. It is used in hydrometers to determine density of fluids.

What are some real life examples of Archimedes' principle?

What are some real life examples of Archimedes ' principle? On entering a bathtub filled with water,an equal quantity of water is displaced as one weight. A ship floats in the sea because of the counter-acting buoyant force from the water based on which safe depth is calculated.

How do you calculate Archimedes principle?

Key Points

  • If an object is completely submerged, the volume of the fluid displaced is equal to the volume of the object.
  • The buoyancy force on hot-air balloons, dirigibles and other objects can be calculated by assuming that they are entirely submerged in air.
  • The buoyancy force does not depend on the shape of the object, only on its volume.

What are the principles of the lever According to Archimedes?

According to Archimedes’ principle, Apparent loss of weight = Weight of the displaced liquid. This apparent loss of weight is the thrust or buoyant force (F b). Therefore, F b = ρ X g X V. It is this force that is responsible for objects to float. Thus, this equation is also called the law of buoyancy.

What is the applications of Archimedes principle in our daily life?

Archimedes principle of buoyancy is applied in our daily life in many ways.
2. Fish, human swimmers, ice bergs and ships float follow Archimedes principle of buoyancy.
Rise of balloon in air also fallows Archimedes principle.

What are the applications of buoyancy and Archimedes principle in our daily life?

1. On entering a bathtub filled with water, an equal quantity of water is displaced as the weight of the person. 2. A ship floats in the sea because of the buoyant force acting from the water.

What is Class 9 Archimedes principle?

Archimedes' principle states that when a body is immersed partially or completely in a liquid, it experience an upthrust which is equal to the weight of the liquid displaced by it.

What are the applications of buoyancy?

Applications of Buoyant ForceSubmarine: A submarine has an enormous counterbalance tank, which is in use to control its position and profundity from the outside of the ocean. ... Hot Air Balloon: The environment is loaded up with air that applies buoyant force on any object. ... Ship: ... Fish: ... Buoyant Force relies upon:

What does Archimedes Principle state?

Archimedes’ principle states that an object submerged in a fluid, fully or partially, experiences an upward buoyant force that is equal in magnitud...

Who discovered the Archimedes’ Principle?

Greek mathematician Archimedes discovered the Archimedes’ principle.

How does the Archimedes’ principle apply to ships?

Archimedes continued to do more experiments and came up with a buoyancy principle that a ship will float when the weight of the water it displaces...

Where is the Archimedes’ principle used?

Archimedes’ principle is used in the design principle of ships and submarines. Hydrometers are based on the principle of Archimedes.

How can the Archimedes’ Principle be used to determine the density?

The weight of the fluid displaced is equal to the buoyant force on a submerged object. The mass divided by the volume thus determined gives a measu...

What is Archimedes' principle?

Archimedes’ principle states that an object submerged in a fluid, fully or partially, experiences an upward buoyant force that is equal in magnitude to the force of gravity on the displaced fluid.

Which principle states that the upward buoyant force exerted on a body immersed in a fluid, whether

Archimedes’ principle states that: “The upward buoyant force that is exerted on a body immersed in a fluid, whether partially or fully submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid”. The value of thrust force is given by ...

What is the principle of buoyancy?

Archimedes continued to do more experiments and came up with a buoyancy principle that a ship will float when the weight of the water it displaces equals the weight of the ship and anything will float if it is shaped to displace its own weight of water before it reaches the point where it will submerge.

What is the instrument used to measure the relative density of a liquid?

A hydrometer is an instrument used for measuring the relative density of liquids. Hydrometer consists of lead shots which makes them float vertically on the liquid. The lower the hydrometer sinks, the lesser is the density of the liquid.

What is the Archimedes principle?

Archimedes principle formula states that a fluid exerts an upward thrust on a partially or fully immersed body, which is known as buoyant force. Due to this force, the body faces an apparent loss of weight. The apparent decrease in weight is equal to the magnitude of the buoyant force.

What is Archimedes law?

Using Archimedes law, the volume or density of any rigid body can be computed. The proportions of the constituent metals of an alloy can be easily calculated using this principle.

Who is Archimedes in Greek?

Archimedes was a Greek mathematician, physicist, astronomer, engineer, and inventor , born in Syracuse of Sicily. He gave the theory of buoyancy and started the study of hydrostatics. He proved various geometrical theorems (e.g. volume and area of a sphere, area of a circle) using the concept of “infinitesimals” far before the advent of modern calculus. One notable invention of his was the Archimedes’ Screw, which was used to pump water from low lying areas to irrigation channels.

Calculation of Buoyant Force

The force on the bottom of a submerged object is greater than that on its top because pressure increases with depth. Therefore, the fluid exerts a net upward buoyant force on the object . Consider a submerged cylinder as shown in figure (1)

1 . Floatation of Ships

We know that an iron coin sinks in the water but large ships do not ? The reason behind that is Archimedes’ principle.

2 . Hydrometer

A Hydrometer is an instrument that is used to measure the specific gravity or density of the liquids . It works on Archimedes’ principle . A hydrometer floats on liquids for the same reason that a ship floats on water.

3 . Hot air balloon

The principle behind hot air balloon is the Archimedes Principle . It states that the buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object . Here balloon is a submerged object in fluid ( air ) . For a hot air balloon , the upward buoyant force acting on it is equal to the weight of air displaced .

4 . Lactometer

Lactometer is a small glass instrument that is used to test the purity of the milk . It works on the Archimedes’ principle . It measures the specific Gravity of milk ( relative density of milk with respect to water ) . If the specific gravity of a sample of milk is within the approved ranges , the milk is pure otherwise not .

5 . Submarine

A submarine does not lift weight , it can carry it but it is the water that does the lifting .

Solved Examples

Example 1 . Density of ice is 900 kg/m 3 . A piece of ice is floating in water density 1000 kg/m 3 . Find the fraction of volume of the piece of ice outside the water .
