Difference between Normal Stress & Shear Stress
The relationship between the stress and strain that a particular material displays is known as that particular material's stress–strain curve. It is unique for each material and is found by recording the amount of deformation (strain) at distinct intervals of tensile or compressive loading (stress). Stress–strain curves of various materials vary widely, and different tensile tests conducted on the same material yield different results, depending upon the temperature of the specimen and the speed of the loading. It is possible, however, to distinguish some common characteristics among the stress–strain curves of various groups of materials and, on this basis, to divide materials into two broad categories; namely, the ductile materials and the brittle materials.

In this session, Educator Praveen Kulkarni will discuss Plane Stress vs Plane Strain. This session will help students to get a fundamental understanding of the topic in a very clear manner. This session will be beneficial for all students who are preparing for GATE and ESE in the upcoming years. Educator Praveen Kulkarni will use models in this session to explain the topics with even more clarity.

This mechanics of materials tutorial introduces the concept of pure bending. It’s important to follow the sign convention provided. An easy way to remember is that positive internal bending moment makes a beam “smile” and negative internal bending moment makes the beam “frown.”
In this video we explore bending and shear stresses in beams. A bending moment is the resultant of bending stresses, which are normal stresses acting parallel to the beam cross-section. We can easily derive an equation for these bending stresses by observing how a beam deforms for a case of pure bending. This equation is know as the flexure formula.

In this video we will explore torsion, which is the twisting of an object caused by a moment. It is a type of deformation. A moment which tends to cause twisting is called torque.
