# Strength of material OR Mechanics of solid

Learn FUNDAMENTALS of Strength of material OR Mechanics of solid for academic proficiency & competitive examinations.
Instructor:
J Aatish Rao
29 students enrolled
Good grasp over SOM - Strength of material topic of their academics
Understanding of topics like Beams,Stress strain relationship, stress components, elastic constants & many more

This course is designed specifically for students those have a bit lacking in core knowledge. The main idea behind these 7-8 lectures is to infuse in the minds of young ones, the fundamental concept behind strength of material. Topics covered are :- Stress strain relationship, true stress & strain, elastic constants, Bending & shearing stress, Beams & many more along with a bonus lecture containing important formulas & tips.

### Basic Introduction

1
Introduction to Strength Of Materials

Basic introduction to strength of material. Pardon me for the background noise. In this course you will be going to be enlightened about the topic in most concise & elementary way. Watch & download each of the lectures & revise when you like.

### Common terminology, Stress strain relationship & more

1
Stress - Strain relationship

Stress is a force acting on a rock per unit area. ... Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stressStrain is a change in shape or size resulting from applied forces (deformation). Rocks onlystrain when placed under stress. A brief description about the relationship between the two is elaborated in this lecture. Feel free to download & learn.

2
Elastic constants, True stress & strain

True stress (σ') and true strain (ε') are used for accurate definition of plastic behaviour of ductile materials by considering the actual (instantaneous) dimensions.A brief description about the same is elaborated in this lecture. Feel free to download & learn.

Elastic Constants - Stress produces strain. But how much strain is produced depends upon the solid itself. The solid is then characterized by an elastic modulus that relates strain to stress.

Quiz 1 - Test your knowledge

Based upon lecture 2 & 3 i.e stress-strain relationship & elastic constants.

### Mohr's Circle, MOI & Bending stresses

1
Plane stress, Plane strain & Mohr's Circle

Mohr's circle, named after Christian Otto Mohr, is a two-dimensional graphical representation of the transformation law for the Cauchy stress tensor.A brief description about the same is elaborated in this lecture. Feel free to download & learn.

2
Bending & shear stresses

Normal stress is a result of load applied perpendicular to a member. Shear stress however results when a load is applied parallel to an area. Looking again at figure one, it can be seen that both bending and shear stresses will develop. Like in bending stressshear stress will vary across the cross sectional area.A brief description about the same is elaborated in this lecture. Feel free to download & learn.

3
Second moment of inertia.

The 2nd moment of area, also known as moment of inertia of plane area, area moment of inertia, orsecond area moment, is a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis.A brief description about the same is elaborated in this lecture. Feel free to download & learn.

### Bonus lecture with important formulas

1
BEAMS

beam is a structural element that primarily resists loads applied laterally to the beam's axis. Its mode of deflection is primarily by bending.A brief description about the same is elaborated in this lecture. Feel free to download & learn.

2
Important Formulas

Important formulas for Strength of material. Covering major topics explained in the lectures.
