Hello everyone, and welcome to another video on the Efficient Engineer channel! In this video we’re going to take a look at a really interesting material property, Poisson’s ratio. Poisson’s ratio is such an important material property because it gives …

bookmark_borderUnderstanding Young’s Modulus
Welcome back to the Efficient Engineer channel everyone! In this video we’re going to talk about Young’s modulus, one of the three main elastic constants along with shear modulus and bulk modulus, which are used to describe how a material …
bookmark_borderUnderstanding Viscosity
Thanks to CuriosityStream for sponsoring this video. Everyone has an intuitive understanding of what the viscosity of a fluid is. Honey is more viscous than oil, and oil is more viscous than water. Viscous fluids feel thicker, and don’t flow …
bookmark_borderUnderstanding Laminar and Turbulent Flow
This video from The Efficient Engineer is sponsored by Brilliant. One of the very first things you learn in fluid mechanics is the difference between laminar and turbulent flow. And for good reason – these two flow regimes behave …
bookmark_borderUnderstanding Fatigue Failure and S-N Curves
Components which are subjected to loading which varies with time can fail at stresses well below the material’s ultimate strength. This is known as fatigue failure and it accounts for the vast majority of mechanical engineering failures worldwide. The bolts …
