When you are talking about solids and various other materials, it is crucial to understand how these types of materials usually react when a force is applied. This process helps the students identify their strengths, deformations, and various other parameters acting on the objects, by calculating the various types of forces acting on them. And in order to find these parameters, the stress and strain quantities are important, and here in this article, we are going to provide a detailed guide about them below.

What is Stress?
Stress is defined as the force per unit area that is observed, in different types of materials, when an external force is applied. These external forces are generally uneven heating, permanent deformation, etc.

Types of Stress
There are different types of Stress that can be applied to a material, such as,

Compressive Stress
When a force acts on a body, it causes a reduction in the volume of the said body, resulting in deformation. This type of stress is referred to as Compressive stress.

Tensile Stress
When an external force is applied per unit area on a material, and it results in the stretching of the said material, then it is described as Tensile Stress.

What is Strain?
If a body experiences deformation due to the applied external force in a particular direction, then it is called strain. Moreover, the strain does not have any dimensions, as it only explains the change in the shape of the object.

Types of Strain
Similar to stress, strain is also differentiated into Compressive Strain and Tensile Strain.

Compressive Strain
Compressive strain is defined as the deformation observed on an object when compressive stress acts on it. And in this type of strain, the length of the material or object generally decreases.

Tensile Strain
The Tensile stress acting on a body or a material that causes the increase in the length of said material is referred to as a tensile strain.

Stress-Strain Curve
This graph explains how stress and strain act on a body with respect to each other, as well as the different regions formed on the graph.

The OA line represents the Proportional Limit, as it described the region, where the material or body obeys Hooke’s Law. And this line can help students to calculate Young’s Modulus, using the ratio of
Stress and Strain Curve.
Now, the AB line represents the Elastic Limit of the object, which means that after this point, the body does not retain its original shape or size, when the acting force is removed.
As you can guess, the BC lines describe the Yield Point. Which, when force is applied on the material, then there is complete deformation in the object, which cannot be reversed, even if the force is removed.
D point on the graph is the point beyond which students can observe the complete failure of the object, as it crosses the maximum stress a material can endure. This point is stated as Ultimate Stress Point.
E is the Fracture of Breaking Point, at which students can observe the complete failure of deformation of the object, regardless of the force whether it is applied or removed.
Hooke’s Law
From the above sections, we have learned all about types of stress and strain, and their units, as well as a graphical representation of stress and strain on objects. Now let us talk about Hooke’s law of stress and strain, which plays an important role in helping us understand how stress and strain work on an object when force is applied.

According to this principle, the strain of the material is equal to the applied stress, in the elastic limit region of the said object or material. And it is represented as,

F = –k.x

F = Force

X = Extension of Length

K = Spring Constant

In the above article, we have explained in detail the terms, stress and Strain, how they act, units of stress and strain, types of stress and strain, etc. This will be helpful for students to solve any kind of problems from these chapters, or understand other subtopics easily from the next chapters. However, if you are still worried, about how to cover a large number of complex topics and chapters in Physics. Then the best solution for you is to join Online Coaching Platforms. Like the Tutoroot platform, which offers cost-effective online interactive classes that come with various amazing benefits for the students.

India is a great place to pursue an online MBA program. There are many advantages to studying in India, such as the diverse culture and the abundance of opportunities. However, there are also a few drawbacks to consider before enrolling in an online MBA program in India.

1. What is an online MBA program?

An online MBA program is an MBA degree that can be earned through a distance learning program. This type of program allows students to take courses and earn their degrees without having to attend classes on campus. Instead, students participate in online courses, which can be completed at their own pace.

2. The pros of online MBA programs in India

There are several pros to pursuing an online MBA program in India. The most obvious benefit is that you can study from anywhere in the world, as long as you have an internet connection. This flexibility is ideal for working professionals who want to continue working while they pursue their degrees. Additionally, online MBA programs in India are often more affordable than traditional MBA programs.

Another advantage of online MBA programs is that they offer a lot of flexibility in terms of course choices. You can choose to specialize in a particular area of business or study a variety of courses. This variety allows you to gain a well-rounded understanding of the business world.

Finally, online MBA programs in India are often very well-regarded. They are often seen as being on par with or even better than traditional MBA programs. This reputation can help you when you are looking for a job after graduation.

3. The cons of online MBA programs in India

There are a few disadvantages of online MBA programs in India when compared to traditional programs. The first is that online programs are often not as prestigious as traditional programs. This is likely because online programs are relatively new, and many employers may not view them as being as rigorous as traditional programs. Additionally, online programs may not offer the same networking opportunities as traditional programs. This is because traditional programs often have on-campus recruiting events and networking opportunities, while online programs do not. Finally, online programs may not be as affordable as traditional programs. This is because traditional programs often receive scholarships and financial aid that are not available to online students.

4. How to choose the right online MBA program in India for you

There are a lot of online MBA programs in India to choose from. How do you know which one is the right one for you? Here are some tips to help you choose:

1. Do your research. Make a list of the programs that interest you and research them thoroughly. Look at the curriculum, the faculty, and the reviews from past students.

2. Consider your goals and needs. What are you looking to get out of an MBA program? Consider the school’s focus and whether it matches your goals.

3. Compare the costs. Make sure you compare the tuition, fees, and other associated costs of the programs you are interested in.

4. Consider the location. Do you want to study in a big city or a smaller town? Do you want to study in India or abroad?

5. Consider the culture of the school. Do you want a traditional Indian program or one that is more international?

6. Talk to alumni. Ask alumni about their experiences in the program and how it has helped them in their careers.

7. Take the GMAT. Most schools require you to take the GMAT before admission. Make sure you are prepared for this test.

8. Apply! Once you have narrowed down your choices, apply to the schools that are the best fit for you.

5. Conclusion

Overall, the pros of studying for an online MBA program in India outweigh the cons. If you are looking for a challenging and rewarding experience, India is a great place to pursue your MBA.
