What is Stress and Strain Curve?

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.

Changing Careers? Avoid These 5 Classic Mistakes

The average person can expect to change careers (not just jobs) 3 to 5 times in their working life. Avoid the 5 classic mistakes most career and job changers make.

Most of the experts say that the average person can expect to change careers (not just jobs) 3 to 5 times in their working life. The reasons? Many people are burnt-out, underpaid, stressed out, bored, unsatisfied, or at a career dead end. For some, their careers have changed on them –thanks to corporate mergers, changes in technology, company restructuring, age discrimination, and a thousand other reasons. After counseling thousands of people in finding new careers and jobs, we have found that there are 5 classic mistakes most career and job changers make:

MISTAKE 1: NO CLEAR GOAL.

Not having a clear goal is like trying to run a race when you do not know where the finish line is. Many career changers have only a partial goal. They KNOW that they want a job with less stress, or more money, or more of a future, or more independence, or more satisfaction. A career goal, however, should be comprehensive, specific, clear, and realistic. It should include not only the practicalities of your situation, but also who you are, the realities of the job market, and the potential pitfalls.

MISTAKE 2: NO CLEAR PICTURE OF YOUR STRENGTHS.

Most career changers (and job seekers) spend more time worrying about their weaknesses than their strengths. Most people don’t even know what their strengths are. But it is your strengths–not your weaknesses–that determine your career success. Get a professional assessment. This should also include your personal characteristics, motivation, aptitudes, goals, values, interests, and talents. A career and job decision is too important not to have this picture.

MISTAKE 3: NO CAREFUL PLANNING.

Sure, most people think about it for a long time, but thinking is not the same thing as detailed planning. Most people plan a night out with friends more carefully than they plan their careers. Planning would mean researching the new career, talking to people who are in the new career, getting some hands-on experience, reading (books, trade journals, industry newsletters), developing strategies for any possible negatives or problems, consulting with a mentor, knowing what education or training you would need, and other actions.

MISTAKE 4: NO MOTIVATION.

As a psychologist who has worked with underachievers of all ages, I can tell you that many have good intentions but fail to take action. This is, of course, a normal human trait. There are times when all of us procrastinate, give ourselves excuses, and do not do the things that will lead us to our goals. If you are changing careers, however, you had better be motivated. Only consistent, daily, well-considered action will get you where you want to go.

MISTAKE 5: NO INDIVIDUALIZED JOB SEARCH STRATEGY.

If you are changing careers, you need something more than the usual job search tactics. You need a strategy that fits who you are as a unique individual and the fact that you are changing careers. For example, if you tell a job interviewer (or anyone else) that you are “changing careers,” it is the kiss of death. You see, if you are changing careers, then you are starting over–from square one–and are competing with kids just out of school. Instead, you should say, “I am taking the next step in my career” (which, actually, is closer to the truth for most career changers). Another example: Make sure your résumé is rewritten so that it doesn’t “lock you in” to the old career. Go light on the jargon. Emphasize skills in the old career that would be a real advantage (not just “transferable skills”) in the new career. If you avoid these classic mistakes, you are well on your way to making a successful job and career change.
