Introduction to Course

Here we discuss the basics of principle stresses. We learned formulas very important for GATE, ESE and PSUs. Formulas of normal stress and shear stress as a finding of angle. Also we learned the formula, assumptions and conventions of maximum and minimum principle stress.

Principle Stresses : Basics and Important Formulas for GATE, ESE & PSUs

Here we discuss the concept of mohr's circle. Conversion of state of stress to mohr's circle.

Mohr's Circle - 1 : Basics

Here we discuss the concept of maximum absolute shear stress and maximum in plane shear stress.

Mohr's Circle - 2: Absolute Maximum Shear Stress

In this lecture we discussed how to draw mohr's circle in presence of shear stress. We also discussed formulas for finding principal stress if principal strain is known and finding principal strain is principal stresses are known. Also we discussed strain rosette which was included in GATE Syllabus in 2016.

Mohr's Circle - 3: Strain Rosette and Drawing Mohr's Circle in Presence of Shear Stress

Here we discuss why theories of failures are required. Also we had a brief discussion on maximum principal stress theory.

Theories of Failure #1: What Is the Need of It?

Here we discuss where MPST is under safe and in which condition it is over safe. We also discussed why MDET is the most accurate method.

Theories of Failure #2 : Maximum Principal Stress Theory

Here we discussed maximum shear stress theory and also why maximum shear stress theory is always over safe.

Theories of Failure #3 : Maximum Shear Stress Theory

Here we discuss maximum distortion energy theory (Von-Mises and Hencky) and Total strain energy theory (Heigh's Theory)

Theories of failure #4 : Maximum distortion energy theory

Here we discussed maximum principal strain theory (Von-Misses theory) and Mohr's Theory of failure.

Theories of failures #5 : Maximum Principal strain theory & Mohr's theory

Here we have a comparison of theories of failure. We find out when to use which theory of failure.

Theories of failure #6:comparison of different theories of failures

Here we discuss the basics of columns. We talk about Euler's Buckling load, slender columns, equivalent length, different types of columns based on supports and a lot more.

Columns #1 : Basics

Here we have an in depth discussion on columns and Slenderness Ratio.

Columns #2 : Slenderness Ratio, Rankine's crippling load

Here we discuss Rankine's theory, secant formula, perry's formula, Johnson's line, Euler's line and how the curve of buckling be sinusoidal.

Columns #3 : Rankine buckling load

Here we discuss thin pressure vessel. We get a brief idea of what are longitudinal stresses, hoop stresses, radial stresses. How to differentiate between thick and thin pressure vessel.

Pressure vessels #1:Basics, thin pressure vessel

Here we discussed :
- cylindrical pressure vessels
- Why we use cylindrical pressure vessels to store liquid nitrogen.
-important formulas for spherical pressure vessel.

Pressure vessel #2: Volumetric strain, thick pressure vessel

Here we have a discussion on pressure vessel strengthening mechanisms :
- autofrettage and wire winding
- Compound cylinders

Pressure vessels #3: Auto-frettage & wire winding

Here we discuss longitudinal stress, radial stress and hoop stress distribution in case of thick pressure vessels.

Pressure vessel #4 : Thick pressure vessel

Here we discuss torsional stress distribution in case of rectangular bars, St. Venant's principal and I tried to motivate you guys for competition.

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.
