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

What is Stress in the Strength of Materials?

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

Stress Strain Curve – Relationship, Diagram and Explanation

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

What is First Moment of Area?

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

Unlocking the Secrets: Understanding Mechanical Properties of Materials

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 And Strain?

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 Strain – Strength of Material?

What is strain?, this is a simple and common question generally asked by a person who goes to study about strain in the strength of material. In this post, I will try my level best to explain you about strain and its types. What is strain? When an external force is applied on a body,

What is Centre of Gravity and Centroid of a Body?

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

What is Stress in Mechanics of Solids ?

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
