First Law of Thermodynamics

The word thermodynamics is the combination of therm and dynamics. The word “therm” stands for thermal. In simple words, thermal means heat. The word “dynamics” relates to the branch of mechanics. Thermodynamics states the relationship between heat, temperature, work, and energy. There are four laws of thermodynamics. However, this article will only cover the first […]

Elastic stress and strain

When a material undergoes loading, deformation takes place. This deformation may be elastic or plastic. So what is elastic and plastic deformation? If the body regains its shape and size after removal of deforming force then that deformation is called elastic deformation and the body is called elastic body. If it does not regain its

Elastic Collisions

Introduction In contrast to an inelastic collision, when kinetic energy is lost during the collision, an elastic collision occurs when numerous objects collide and the overall kinetic energy of the system is preserved. The law of momentum conservation applies to all sorts of collisions. Most collisions in the real world result in the loss of

Bernoulli’s Theorem and Its Applications

Bernoulli’s theorem deals with fluid dynamics and how the pressure of fluid changes depending on the velocity of flow. It was named after Daniel Bernoulli, a Swiss mathematician (1700-1782). Although Daniel Bernoulli discovered the principle, Leonard Euler was the one who developed it into the Bernoulli equation we use today.  The principle finds its applications

Bayes Theorem Introduction

In probability theory and statistics, Bayes Theorem (or Bayes’ Law or Bayes’ Rule) asserts that the likelihood of an event increases when previous information or knowledge of conditions is provided. Suppose cancer is linked to age, for example. In that case, Bayes’ theorem can be used to assess the chance that a person has cancer

ZEROTH LAW OF THERMODYNAMICS

Based on the other three laws, zeroth thermodynamics law is formulated. Still, at the time of discovery, lots of confusion occurred about the naming, whether to name it as fourth law or something else. This confusion got sorted as a clear definition of temperature and its occurrence. Hence, it is named Zeroth law of thermodynamics.

Young’s modulus

Young’s modulus Young’s modulus can be defined as the property of a given material which can determine the point of its stretching and breaking. Young’s modulus is defined as the ratio of tensile stress to tensile strain. Tensile stress can be defined as the resistance of an object to an external force that could potentially

Yield Strength

Yield strength is a word that refers to the greatest stress that may be created in a material without causing it to deform plastically. Yield strength is a good estimate of a material’s elastic limit. It is defined as the stress point at which a material becomes permanently deformed. The material will bend elastically before

Wien’s law

Wein’s law establishes a link between the wavelength of light with the greatest intensity and the object’s absolute temperature. In other words, Wein’s displacement rule explains why things produce a spectrum of distinct wavelengths at different temperatures. For example, hotter items emit shorter wavelengths, which gives them a reddish hue, but cooler objects emit longer
