## what is Girder? How Girders are different from beams?

Girder is a member of structure framing system. Beams and girders both have same function. Both of these members carry and distribute structure load. Many people think that both beams and griders are same thing but that is not true. Both of them have same functions but there are some key differences which separate them …

## Theory of Failure considered for Machine Design

Theory of failure describe the elastic failure of the mechanical components. At the time of working machine components subjected to various loads which cause different types of stress in it. Theories of failure help us to determine the safe dimensions of the machine components when they are subjected to bi-axial or tri-axial state of stresses. …

## What is Fatigue Failure?

We know about fatigue and feel it many times in our body after long workout. Similarly engineering components are also fails due to fatigue. Fatigue failure in any engineering component occurs when these components are subjected to cyclic loading or we can say that the fluctuating stresses are induced in the components. Fatigue is the …

## Relation between Young Modulus, Bulk Modulus, Modulus of Rigidity and Poisson’s Ratio

Today we will learn about relation between Young Modulus, Bulk Modulus and Modulus of Rigidity. All of these are elastic constant which are used to design any machinery part or structure. We have discussed about these three constant in our last post and know all of them are ratio of stress to strain in different …

## Elastic Constant : Bulk Modulus, Modulus of Rigidity and Poisson’s Ratio

Hello friends. Today we are going to learn about some important definition used in study of SOM like bulk modulus of elasticity, modulus of rigidity and Poisson’s ratio. In our previous articles, we have learnt about strain, stress and their types and relationship. We have also discussed about young modulus of elasticity in my last …

## What is Young Modulus of Elasticity

Today we are going to learn about elastic constant or more appropriate young modulus of elasticity. In our previous articles we have learnt about strain, stress and their types and relationship. In stress strain curve article, we have learnt about proportional limit and I have discussed about a constant there. This constant is known as …

## Stress Strain Curve : Full Explanation

Hello Friends, I hope you are doing well. In our previous articles we have learnt about what is stress, strain, types of stress and strain etc. In this article we are going to discuss about stress strain relationship and also learn about stress strain curve which is very important to predict any material behavior when …

## What is Stress? What are main Types of Stress?

In my last lecture we have learnt about strain and types of strain. Today we will learn about types of stress. We know that when a body is under loading some kind of stress developed in it. Mathematically this stress is the ratio of the applied force to cross section area of the body. If …

## What is Strain? What are Types of Strain?

Hello friends, Hope you are doing well. In our last lecture we have studied about stress and strain. We have learnt about basic concept behind it. Strain is a measurement quantity which is ratio of change in length to original length under loading condition. But when we stretch a body, its dimensions changes in all …

## What is stress and strain?

Hello guys… I hope you are doing well in your study. I generally write articles on Automobile, Production etc. But now we are going to start to provide best quality articles on strength of material which is an interesting subject and also a very important as exam point of view. It is our first article …
