An introduction to the course. I am an X-BARC scientist teaching a course covering SFD, BMD, deflection of beams and torsion.

Introduction

Here we discuss sign convention for sfd & bmd, different types of beams like simply supported beams, cantilever beams, propped cantilever beams and continuous beams.

An Introduction to SFD and BMD

Some examples on SFD & BMD. What kind of beans are statically indeterminate.

SFD and BMD 2

Few more examples of shear force and bending moment diagram

SFD and BMD 3

SFD and BMD 4

Here we discuss the curvature of bending moment diagram. It is a very important concept for GATE, ESE, PSUs etc and students often get confused in it. It is very easy to understand and you'll find it out in this lecture.

SFD and BMD 5 Curvature of BMD

Some more escapes of SFD & BMD  for GATE, IES, PSUs.

SFD and BMD 6

If you can solve this SFD BMD problem, you can solve any SFD BMD problem. This is the most complicated problem in strength of Materials,synthesised to make you concept crystal clear.

SFD and BMD 7 Most complicated numerical in SFD & BMD

Here we discuss deflection of beams. We stay with basics and discuss where slow will be maximum of you are having symmetrically loaded beam and where will it be if it is not symmetric. Here I also discuss double integration method and how to use it to get shear force and loading distribution.

Deflection of Beams #1:Introduction and double integration method

Derivation of slope and deflection for cantilever beam with point load at free end using double integration.Also here we discuss some important formulas for slope and deflection of various loading configurations like cantilever beam with uniformly distributed load.

Deflection of Beams #2 : formulas of slope and deflection for various loading configurations

Here we discuss some more formulas for deflection of beams for simply supported beams and cantilever beams. I've also discussed some of the tricks of memorization to remember these formulas at any time. At the end I've given a formula for total selection of a bar with rectangular but varying cross section. All these formulas are very important for your competitive examinations like GATE, ESE, PSUs, BARC, ISRO, DRDO etc.

Deflection of Beams #3.1: Some more formulas important for GATE, ESE and PSUs

Here we discuss 2 of the most important methods to find deflection of beams i.e. Castigliano's methods and moment area methods. We also discussed a numerical very important for competitive examinations like GATE, ESE and PSUs where we find deflection of cantilever beam when free end is supported by a spring.

Deflection of Beams #3.2 : Moment area method and castigliano's method

Here we discuss two examples of castigliano's theorem so that we understand the theorem by its application :
1) To find the deflection of circular beam, hinge support at one end and roller support at other end.
2) To find the slope of simply supported beam with concentrated moment at mid point.

Deflection of beam #3.3 - some examples of castigliano's theorem

This is an introduction to transverse shear stress. Here we take a look at derivation of transverse shear stress across the cross section of a rectangular beam.

Shear stress #1: Derivation of shear stress distribution for rectangular bar.

Shear stress distribution in various cross sections like T, I, +, triangular, rectangular, diamond etc. and the reason of why we get such a distribution.

Shear stress #2 : Shear stress distribution for various Cross sections.

The discussion is on bending equation, bending stress distributing. Design of belt drive based on bending. Here we answer which belt to prefer to get minimum bending stress and tensile stress.

Bending #1: Bending equation, bending stress in flat belts.

Here we discuss which shape is best to withstand bending. We also discuss few questions of previous year interview questions of BARC and IIT Bombay. Also difference between shear stress and bending stress was discussed.

Bending #2 : Resisting force, best l:b ratio

Here we discuss the absolute basics of torsion. We'll find out what torsional shear stress is and why is it categorised under shear stress. You'll also be introduced to torsion equitation.

Torsion #1: Basics

In this lecture we discuss the concept of shear angle and angle of twist. We also discussed an example on bars in series undergoing torsion.

Torsion #2 : Bars in series

Here we discuss bat's under non pure torsion.

Torsion #3 : Belt tension, non-pure torsion.

This is the end of this course. SOM will be continued in "Strength of Materials : Part 3".  In this lecture we'll discuss bars fixed at both ends and under torsion.

Torsion #4 : Both ends of the bar fixed

I am M Tech from COEP. I have 2 years of teaching experience in Mech Engg. Currently I am trainer in Infosys (Mech Stream).
I love to teach.

Rahul Muthal

This course will guide the students to prepare for Material Science subject. Which will help them in their GATE, IES and other competitive exams preparation for Material Science subject.
This course will also help the students, who are preparing for their university exam of Material Science subject.
In overall this course will help in enhancing the basic concepts of Material Science and knowing interesting relevance of different materials properties and their behaviour.

Shear and bending moment diagrams are analytical tools used in conjunction with structural analysis to help perform structural design by determining the value of shear force and bending moment at a given point of a structural element such as a beam. In this Course, Sanjeev has made an effort to explain all the possible Shear force and bending diagrams of the beam because of loads and moment acting on it. Tags: Shear force and bending moment, Shear force and bending moment diagram examples, How to draw shear force and bending moment diagram, Shear force and bending moment diagram for cantilever beam, Shear force and bending moment diagram solved examples, Shear force and bending moment diagram for fixed beam, Shear force and bending moment diagram for uniformly varying load, GATE preparation.
