Strength of Materials Notes and Study Material PDF Free Download

Strength of Materials Notes: Strength of materials is the kind of theory that is about the behaviour of solid objects that are subject to strain and stress. It is also called the mechanics of materials. The whole theory consists of the behaviour of one or two dimensional members of structures. The states of stress and strain of these one or two-dimensional members could be approximated as two-dimensional. Later it was generalized to three dimensions which created a better theory of the plastic and elastic behaviour of materials.

Stephen Timoshenko was an important founder of this theory. If you are currently studying this theory and looking for study materials, this article will be helpful for you. In this article, we have discussed the complete details about the study materials, syllabus, and reference books of the strength of materials.

Introduction to Strength of Materials

Strength of materials is the study of stress and strain in structural members like columns, beams, and shafts through various methods. The methods that are employed to study the structure members take into account various properties of materials such as its ultimate strength, Poisson’s ratio, yield strength, and Young’s modulus. Proper knowledge of strain and stress of materials helps in the safe design of structures that are capable of intended loads. Structural members develop both strain and stress when a force is applied to it. It is an important part of materials science that needs to be properly understood.

FAQs on the strength of Materials Notes

Question 1.

What is called the strength of materials?

Answer:

Strength of material is the process of calculating the strength and strain of a solid material to know about its capability of withstanding load without failure.

Question 2.

How is the strength of the material calculated?

Answer:

Strength of a material is calculated by checking how much load a material can withstand. Value is determined by dividing the load at the failure by the original cross-sectional area.
