The elastic energy is the mechanical potential energy that is stored in the configuration of the physical system or the material due to the work on the materials, they are subjected to the deformations. Elastic energy occurs due to impermanent stretching or compression of the materials. Primarily, the formalism is developed by the elastic theory, … Read more

The Poisson’a cons ratio is stant for the materials that is used for relating the stress in the one direction, to the elastic strain in another one. The stress usually describes the externally applied force to the materials and the strain is the measurement of the change in the shape due to the applied force. … Read more

The shear modulus is also known as the modulus of rigidity, and it is the measurement of the rigidity of the material or body given by the ratio of shear stress to shear strain. Often it is denoted by the G or sometimes by the μ or S as well. Units of Shear Modulus of … Read more

It’s well known that plants absorb water from the soil in the process of photosynthesis. But have you ever wondered how this happens? For water to rise up, it has to work against gravity and yet it does happen. This is another phenomenon which occurs because of the surface tension of liquids. If water is … Read more

The bulk modulus is a constant for describing the resistance of the substance to the compression. It is defined as the ratio between the increase in the pressure and the resulting decrease in the volume of the material. Together with the shear modulus, Young’s modulus, and Hooke’s law, this modulus describes the response of the … Read more

The young’s modulus is a numerical constant, named for the English physician (Thomas Young) of the 18th century. This modulus is used for describing the elastic properties of the soil undergoing the compression or tension in only one direction such as the metal rod that is returned to its original length after being compressed or … Read more

Mosquitoes sitting on the water In rainy reason, diseases like dengue and malaria spread by mosquito breeding on fresh stagnant water. They do not sink in water because of surface tension. At the points wherever the legs of the mosquito touch the liquid surface, the surface becomes concave due to the weight of the mosquito. … Read more

One common manifestation of surface tension is the difference in pressure it causes across a curved surface. For simplicity, we consider first a liquid surface that is curved in only one plane but is flat in a direction perpendicular to that plane. The pressures in the different fluids on either side of this interface are … Read more

The viscosity of usually cited as the thickness of a fluid. You’ll think of water (low viscosity) and honey (high viscosity). At a molecular level, viscosity is a result of the interaction between the various molecules in a fluid. This can be additionally understood as friction between the molecules within the fluid. How can we … Read more

Isaac Newton is the founder of the universal law of gravitation and this law of Newton states that every particle attracts every particle in the universe with a force that is directly proportional to the product of their masses and that is also inversely proportional to the square of the distance between their centers. Newton … Read more
