*bookmark_border*Understanding 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_border*Understanding 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 …

Thanks to CuriosityStream for sponsoring this video. Watch thousands of documentaries and get access to Nebula for free, when you sign up using the link in the description. Bernoulli’s **equation** is a simple but incredibly important **equation i**n physics …

*bookmark_border*Understanding 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 …
