Elasticity: Stress-strain relationship

Stress is a measurement of how much deforming force is applied per unit area of an object. Shear and tensile stress are two types of stress in which force is imparted to an item in different ways. When a deforming force is applied at right angles to a surface, it is called tensile stress. Shear […]

The response of different materials to shear deformation is often measured in terms of shear modulus. Shear stress is characterised as the probability of shear stress to shear strain. This ratio is useful in determining how resistant a material is to shearing deformation. If a substance is highly resistant to shearing, the energy produced will

One of the mechanical properties of solids that may be measured is the shear modulus of elasticity. Young’s modulus and bulk modulus are two other elastic moduli. The ratio of shear stress to shear strain in a body is determined by a material’s shear modulus. It can be used to explain how a material resists

Relative density, also known as specific gravity, is the ratio of a substance’s density (mass per unit volume) to the density of a reference material. Water at its densest temperature (4 °C or 39.2 °F) is generally always used as a reference for liquids, while air at ambient temperature (20 °C or 68 °F) is

Stress, strain, elasticity, Hooke’s law and other notions linked to fluids like as Pascal’s law, viscosity, surface energy and so on are all examples of bulk matter properties. Internal restorative force exerted on a deformed body per unit area is known as stress. The strain, on the other hand, is the ratio of the change

A cuboid shaped rubber is pulled by a force F longitudinally. Can you guess what would happen? As force is applied longitudinally, thus the rubber’s initial length will increase, width and the thickness will decrease.The length of the rubber rises by dL, while the width decreases by dB.  What is “Strain”? Strain is defined as

Electrons are found in pairs in most atoms. When electrons are coupled together, their magnetic fields cancel each other out due to their opposite spins. And so, there is no net magnetic field there. Materials having some unpaired electrons, on the other hand, will have a net magnetic field and respond more to an external

It is commonly known that the sun is the densest object in our universe. It is quite interesting to know that there are bodies in the solar system that are denser than the sun. One such body is the neutron star. The neutron star is the densest object in the universe except for black holes.

If a body has a definite shape and size, it is considered rigid. The solid bodies we observe in our environment aren’t perfectly rigid. When an external force is applied to these objects, they deform. However, some items tend to revert to their original shape.  Stress is the internal force acting per unit area of

Introduction Modulus of rigidity is a material’s elastic shear stiffness, usually indicated by the letter G, or sometimes by S, and can be seen as the ratio of the shear stress to shear strain. Shear modulus is the same thing as modulus of rigidity. Shear stress is a component of stress that is parallel to
