# Engineering Mechanics

## What is Engineering Mechanics?

Engineering mechanics is the branch of applied science which works with the laws and principle of mechanics. Whatever the body we seen around us experiences forces and due the forces experienced by the body they undergo motion. The study of object which is either in motion or at rest because of the forces acting on […]

## Types of Support in Structures

In this article, you will learn about different types of support used in structure. There are basically three types of support and these are roller, pinned, and fixed support. There is a fourth support also called as simple support, it is generally not used in structures. Every support has its own field of application. Supports

## Elastic Constants – Young’s Modulus, Modulus of Rigidity and Bulk Modulus

In this article, you will learn about the Elastic Constant – Young’s modulus, Modulus of rigidity, and Bulk modulus. We will also discuss the difference between Young’s modulus, Modulus of rigidity, and Bulk modulus. The various elastic constants in the strength of materials are Young’s modulus or modulus of elasticity Modulus of rigidity or Shear

## What is Poisson’s Ratio in Strength of Materials?

In this article, you will learn about what is poisson’s ratio, longitudinal Strain and lateral strain. We will also find the formula of Poisson’s ratio, lateral strain and longitudinal strain. What is Poisson’s Ratio Poisson’s Ratio: It is defined as the ratio of lateral strain to the longitudinal strain within elastic limit. It means that

## What is Thermal Stress in Strength of Materials?

In this article we will learn about what is thermal stress and formula of thermal stress and strain. What is Thermal Stress? Stress which is induced in a body due to change in the temperature is known as thermal stress and the corresponding strain is called thermal strain. Thermal stress induces in a body when

## What is Beam and Types of Beams in Strength of Materials?

In this article we will discuss about the different types of beams used in the construction. Without beams there will not be any structure which can withstand loads. They are the structural member which helps in bearing loads. If there are no beams, there will be no structure. What is a Beam? The beam is

## What is Elasticity, Elastic Limit, Young’s Modulus and Modulus of Rigidity in Strength of Materials?

In this article, we will learn about what is elasticity, elastic limit, young’s modulus and modulus of rigidity. These terms keeps an important role in the study of subject strength of materials. Understanding about stress and strain is possible when one must have the knowledge of these terms. Let’s discuss about them one by one.

## What is Hooke’s Law? – Strength of Materials

What is Hooke’s law? It is the general question that is asked in the subject strength of materials. This law gives us a relation between stress and strain. It was given by Robert Hooke in 1660. It is defined on elastic materials. What is Hooke’s Law Statement of Hooke’s Law According to Hooke’s law, when

## Units of Stress – Strength of Materials

Before finding the units of stress we must know what is stress and what is formula of stress. It is the formula of Stress through which we can easily determine the Units of stress. Since the stress is defined as the ratio of resisting force or applied load to the cross section area. The formula

## Types of Stress – Strength of Materials

In this article will study the types of stress, normal stress, tensile stress, compressive stress, and shear stress. We will discuss about the definition and formula of each stress in detail. Types of Stress A stress acts on a body may be normal stress or shear stress. Normal Stress: Normal stress is a stress that
