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.

Self-knowledge: The key to finding the right career direction

Your career, like any journey, has a … an end and … For many people, the present … of … is probably not a result of entirely their … If, for some reason, y

Your career, like any journey, has a beginning, an end and a
direction. For many people, the present direction of the
career is probably not a result of entirely their own
choices. If, for some reason, you are not happy with the
direction of your career, there is a way out: Take charge of
your career and change its direction.

1. Know yourself

Has it happened with you that after desperately looking for
something (e.g., keys) all over the place, you eventually
found it right in your pocket or drawer?

That’s exactly the case with finding a new career direction.
Usually, we try to search for a new career direction by
looking all around, for example, at hot jobs, emerging
fields, prestigious companies, friend’s career, what’s safe
and so on. Ironically, we fail to look for the answer where
it actually lies: inside us.

The secret of finding the right career direction is not to
look outside but to look inside. Know yourself and you will
automatically know the right direction for your career.

2. Dig deeper

Most people define themselves is terms of what they write in
their resumes. That’s just the tip of the iceberg. To really
know yourself, dig deeper and uncover your:

(a) Strengths
(b) Personality
(c) Values
(d) Interests

(a) Strengths

Your strength is what you do well and enjoy doing it. We
never fail to admire strengths in top athletes, painters,
writers, leaders but fail to ask “What is my strength?”

Strengths have a solid connection with a person’s career.
According to Peter Drucker, a person can only perform from
his strength. In other words, mediocrity is guaranteed if we
fail to use our strengths. So know your strengths and get
into a career that allows you to leverage your strengths to
the maximum.

Discover your strengths by asking:

- What am I good at and also enjoy doing?
- What makes me feel energized?
- What comes naturally and easily to me?

(b) Personality

Personality is the sum total of a person’s behavioral,
temperamental and emotional traits. For example, some people
are by nature extrovert and enjoy meeting other people. But
some people are born introvert and feel more comfortable
when left alone.

Studies show a direct link between a person’s personality
and his career. Indeed, if you are an extrovert person, you
would do well in roles such as sales, marketing, public
relations. But an introvert person would be better off in
roles that do not require public dealing.

To know your personality in detail and its implications on
your career, appear at personality tests such as Myers
Briggs Test Instrument (MBTI).

(c) Values

Values are what you consider important and valuable. Values
differ from person to person and can range from things like
money, prestige and power to more subtle things like
respect, harmony and independence.

Your values hint towards the kind of work that will suit
you. For example, if you value “achievement, “you would do
well in roles that regularly throw challenges at you.
Someone else, however, may value “helping others” and,
therefore, would do well in occupations that provide an
opportunity to serve others.

To know your values, ask yourself what is important to you,
make a list and prioritize the items. You can also use value
inventories on the Internet to identify your values.

(d) Interests

Should the work be interesting? Yes, for an important
reason: If your work arouses your interest, you are going
to do well. History shows that great achievers always pursued
what fascinated them. Akio Morita shunned the option of joining
the family business of sake brewing to pursue what he was
interested in: an electronics start-up. And he created Sony.

Doing the work that interests you can have a lasting impact
on your career. To uncover your interests, find out what
fascinates you and draws your attention.

Knowing your strengths, personality, values and interests is
like having a compass with its needle pointing towards the
right direction for your career.
