An Introduction to Stress and Strain
This video is an introduction to stress and strain, which are fundamental concepts that are used to describe how an object responds to externally applied loads. Stress is a measure of the distribution of internal forces that develop within a body to resist these applied loads. There are

Normal Stress and Normal Strain | Mechanical Properties of Solids | Don't Memorise
Stress and strain are basically classified into two types of stress and types of strain: Normal Stress/ Normal Strain and Shear Stress/ Shear Strain. To know what they mean, watch the video! (Mechanical Properties of Solids) In this video, we will learn: 0:00 Introduction 0:09 Types of

Turbulence: Reynolds Averaged Navier-Stokes (Part 1, Mass Continuity Equation)
One of the most common strategies to model a turbulent fluid flow is to attempt to model the average, or mean flow field, by expanding the velocity field into an average and a fluctuating component. This video introduces this idea of "Reynolds averaging" and shows how to obtain a mass con

Turbulence: Reynolds Averaged Navier Stokes (RANS) Equations (Part 2, Momentum Equation)
To model the bulk properties of a turbulent fluid flow, we often expand the velocity field into an average and a fluctuating component, substitute into the Navier-Stokes equations, and then average the equations in time. This video describes how to derive the Reynolds averaged Navier-Sto

Understanding Stresses in Beams
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 perpendicular to the beam cross-section. We can easily derive an equation for these bending stresses by observing how a beam deforms for a c

Turbulence Closure Models: Reynolds Averaged Navier Stokes (RANS) & Large Eddy Simulations (LES)
Turbulent fluid dynamics are often too complex to model every detail. Instead, we tend to model bulk quantities and low-resolution approximations. To remain physical, these reduced approximations of the Navier-Stokes equations must be "closed", and turbulence closure modeling is one of t
