In the heart of a vibrant community, tucked away behind a bustling street, lies a haven of tranquility—the local mosque. Within its walls, amidst the serenity of its prayer halls, unfolds a journey of spiritual exploration and enlightenment: the Nazra classes.

With the first light of dawn, as the world stirs awake, a dedicated group of students gathers at the mosque, eager to embark on their daily quest to deepen their connection with the Quran. These are the Nazra classes—a sacred space where the verses of the holy book come to life, illuminating hearts and minds with their timeless wisdom.

As the students settle into their seats, their anticipation palpable, the gentle murmur of prayers fills the air. The teacher, a wise and revered figure in the community, stands before them, his presence commanding respect and admiration. With a soft smile, he opens the Quran, and the journey begins.

The Nazra class is not merely a recitation of verses; it is a voyage of understanding and reflection. Each word is studied with care, its meaning pondered over and its significance cherished. Through the guidance of the teacher, the students learn to navigate the intricate tapestry of the Quran, uncovering its hidden treasures and profound truths.

With each passing day, the bond between teacher and student grows stronger, forged through shared moments of insight and revelation. Together, they explore the depths of the Quran, delving into its teachings on faith, compassion, and resilience. Through stories of prophets and parables of old, they glean lessons that resonate not just in the pages of scripture, but in the fabric of their daily lives.

But the Nazra class is more than just an academic pursuit; it is a journey of the soul. As the students immerse themselves in the verses of the Quran, they find solace in its verses, guidance in its teachings, and strength in its message of hope. In the quiet moments of reflection, amidst the hallowed halls of the mosque, they discover a sense of peace and purpose that transcends the trials of the world outside.

As the sun sets on another day, and the students bid farewell to the mosque, their hearts are light with newfound understanding and their spirits buoyed by the promise of spiritual growth. For in the sacred space of the Nazra class, they have found not just knowledge, but a deeper connection with their faith—a connection that will sustain them on their journey long after they leave its hallowed halls.

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. And to find these parameters, the stress and strain quantities are important. Here, in this article, we are going to provide a detailed guide about these aspects including how we define stress and strain, their types, and difference between stress and strain. Also let us learn about stress formula and strain formula.

Why is it important to study stress and strain?
It is important to study the stress and strain differences and basics, and stress strain curve, all of which will help in ascertaining the amount of stress or load that a material is capable of handling before it breaks, gets distorted, or stretches. So, the study of stress and strain is all about understanding how and why certain materials are more malleable and can be easily deformed or distorted than others.

Stress is defined as the force per unit area that is observed by a material when an external force is applied. These external forces are generally uneven heating, permanent deformation, etc. These in turn help students calculate and find the plastic, elastic, and fluid behaviour of each material under different forces.

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.

Compressive stress leads to material failure that is ultimately caused due to tension. The compressive stress from its application to brittle materials differs from that of ductile materials.

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.

Tensile stress leads to elongation of any material due to external stretching force.

What is Strain?
If a body experiences deformation due to the applied external force in a particular direction, 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.

Let’s understand the stress strain diagram in detail,

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.   
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.  
Difference between stress and strain
In physics, stress refers to the force that is acting per unit area of the object, whereas strain depicts the ratio of the change in an object’s dimension to its original dimension. In physical parlance, stress is equivalent to Pressure and its unit is Pascal or psi, or pounds. On the other hand, strain signifies the ratio of change in dimensions to that of the original dimension, therefore has no units of measurement. Strain, however, can be measured by strain gauges. Stress and strain curve are related, but are characterized by distinct properties. Stress causes deformation, while strain can be caused by several types of stress, including tension or compression.

Difference between plain stress and plane strain
Plane stress happens when the value of normal stress remains zero and the sheer stress which is seen perpendicular to the direction of the applied load is presumed zero. Plane stress is based on assumption and is measured approximately. On the other hand, plane strain is about distortion in the object that is perpendicular to the object’s plane. If plane stress is more of an approximation, then plane strain is more accurate.

Shear stress and shear strain
Shear stress is the stress that is applied parallel to the plane of the object which renders lateral distortion in the object. As far as shear strain is concerned, it reflects the magnitude of lateral strain in terms of tanθ. Shear Strain is shown as tanθ = Lateral Distortion / Perpendicular height.

Stress and strain are fundamental concepts that play a crucial role in understanding the mechanical behavior of materials. The stress-strain curve provides a graphical representation of this relationship, offering insights into the material’s strength, stiffness, and ductility. By studying stress and strain, engineers and scientists can design and analyze structures and materials to ensure their safety, reliability, and performance in real-world applications.

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.

Making a career change is nothing new in today’s job market.

I’ve heard it said that the average American changescareers at least once in his or her life. Long gone arethe days of working for the same company from the timeyou graduate high school or college until that magicalretirement day.

You sure won’t find that kind of loyalty from companies to their workers these days, and it’s rare to find that kindof loyalty from the average worker as well. What withcompanies merging, downsizing, and moving their operationsoffshore, you’d be wise to plan for a career change somewhere along the line in your life.

Of course, losing one job doesn’t automatically mean thatyou can never find another job in the same industry orcareer path. Hopefully, you will. But what if you can’tfind another job? Or what if you don’t really want to? Maybe you’re bored with what you’ve been doing, or you’vegone as far as you can in that career and you’re ready fornew challenges?

Is it really possible to switch to a new career midstreamin your working life?

The answer is a resounding yes! But you have to know how togo about it. It takes a bit of planning, thorough self-assessment, and perhaps additional training.

When I tired of the grind in health administration as anurse, I spent about 2 years trying to figure out what elseI could do. Luckily, I was able to parlay a love and talentfor writing into a new career as a health writer. I did have to prove my ability to write–even though much of myjob responsibility in my previous healthcare administrationjob did involve writing. I was fortunate enough to be able to use networking and some lucky breaks to get into thecareer I wanted with a minimum of effort.

My partner, Jim, has been a systems engineer for more than20 years, but graduated with a bachelors degree in math originally. When he began to search for a career changealternative, his path was not quite as clear as mine hadbeen. Finally, though, after spending quite a bit of timeon self-assessment, he honed in on his love for trainingand teaching. But you can’t just move into the field ofteaching with no experience or education. Fortunately, theshortage of qualified teachers–especially in certain highneeds areas–has led to the development of a number of “alternative path” programs for teaching. Jim has enrolledin just such an online program out of Montana State University and will be launching his new career later thisyear as a high school math teacher!

So, the question is… once you’ve figured out what you want to do in your new career and you’ve gotten the training you need, how do you sell yourself to a newemployer?

The first thing you want to consider is the format for yourresume. The traditional chronological resume format is notyour best choice for a career change. Instead, you want touse either a functional–or even better, combination–format. You can read more about the different types of resume formats here:http://www.powerful-sample-resume-formats.com/formats

Second, you need to take a look at your transferable skills. That is, what current or past experience or skillsdo you possess (either from past jobs or in your personallife) that you could use in your new career?

For example, one of my readers recently asked how hecould get into interior design without any previous jobexperience or training. I’m not sure you CAN get intothis field without any training, but if so, then Iadvised him to look at any design experience he’s had,perhaps with redecorating his own or a friend’s home. Ialso encouraged him to build a portfolio of his work,which can be a very effective way to get an employer’s attention.

Thirdly, you have to be honest with yourself about whetheryou can really make a career change without adding to yourskills and credentials by getting some training in the newfield. There’s a lot to be said for the contacts you can make during such training too, that may help you networkwith people who can provide an entree into the new career.

In summary, anyone can make a career change if they reallywant to. But to do so, you’ll need to know what related skills and experience you bring to the table. And you’llneed to know how to sell yourself to a prospective employer. Career change is inevitable… you can count onit! But make sure it’s on your terms by making a solidcareer change plan.
