Everyone has different learning power. For some of the people, getting information from just a textbook is the best way to absorb new info. Others are more comfortable to gather information that is presented them in the form of spoken words.

The online learning environment plays a very important and powerful platform to conduct various experiments, explore how students learn and how the faulty can teach. Furthermore, here at Ekeeda, we are continuously listening to the wants and needs of our community, with the aim of enhancing the learning experience of students and improving the learning and teaching via online mode.

Whether you are learning any course via Ekeeda or challenging yourself to learn more and more at your current job, identify your style of learning can help you to become better and more efficient learner.

As soon as you came to know your learning style, you can make customization in your approach- starting from the best way to study the most efficient way to gather information. Take a look and use these ideas to work this winter, by signing up for a course at Ekeeda.

Strength Of Materials:

#Introduction:-

In earlier studies we have undergone a basic course in mechanics of Rigid Bodies, more commonly referred to as Engineering Mechanics or Applied Mechanics. Mechanics as such is subdivided into three branches; Mechanics of Rigid bodies, Mechanics of Deformable Bodies and Mechanics of fluids.

Mechanics of Rigid Bodies assumed bodies to be perfectly rigid i.e. there is no deformation of bodies under the action of loads to which they are subjected statics and Dynamics are the two branches of Mechanics Of rigid Bodies involving stationary and moving bodies respectively under the action of loads.

Stress:-

I. The force of resistances per unit are offered by a body against deformation is known as Stress. When a body is subjected to external loading the body undergoes some deformation. At the same time internal force of resistance is due to the cohesion of molecules inside the body. Thus stress is induced in the body upon external action of load

ii. If the body is able to resist the external load, it is said to be stable, in equilibrium and therefore for this condition the internal force of resistance should be equal to the external load.

By Definition Stress=force of resistance/cross sectional area

Or Stress=P/A

  • Strain:-

As the body produce force of resistance to counter the external loading it undergoes some deformation.The extent of deformation depend on the material property like molecular cohesion.The ratio of change in dimension is known as strain.

Since Strain is ratio, it has no units. We shall denote strain by letter e. If L is the original dimension and is change in dimension and then

Strain =Change in dimension/Original dimension
