In mechanics of solids, the knowledge of difference between stress and strain is very important. When an external force is applied on a body, it starts to deform. the external force applied on the body induces a resisting force within the body, when this resisting force is taken on unit area is called stress. There […]

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
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

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

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? 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
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
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
In this article, you will learn about what is stress in the strength of materials, their unit, and types of stress with numerical problems. So let’s begin our study… What is Stress? Stress is defined as the resistance force acting per unit cross-section area of the body. It is also defined as the ratio of
In this article, we will Study About the stress-strain curve relationship, diagram and explanation. It is the graphical representation of the stress against strain for a ductile material. A tensile test is conducted in order to get the stress-strain diagram. What is Stress-Strain Curve? Stress strain curve is the plot of stress and strain of

In this article, we will discuss about the definition of the first moment of area or moment of area, application, and example. We will also derive the formula for it. First Moment of Area Considered a thick lamina or a body having area A. let x is the distance of C.G. of the area from
In this article, we will learn about the various mechanical properties of materials. Knowing about them is very important to identify any material. It is the mechanical properties which provide the correct information about where the materials can be used. They are the measure of strength and how long the material can exist in its

What is Stress? Whenever an external force is applied on a body then a resisting force is induced in the body. This resisting force acting per unit area of the body is called stress. Under equilibrium condition this resisting force is equal to the applied load. So the stress is also defined as the ratio
What is Centre of gravity Centre of gravity of a body is defined as the point through which the whole weight of the body acts. A body can have only one centre of gravity for all positions of the body. It is represented or denoted by C.G. or G. What is Centroid The point, at

In order to understand the subject mechanics of solids (or strength of materials) , first we must know the meaning of strength of materials. When an external force is applied on the body in the form of push or pull, the body tends to undergo some deformation. But due the existence of cohesive forces between
