Reaching breaking point: Materials, Stresses, and Toughness:

Today we’re going to start thinking about materials that are used in engineering. We’ll look at mechanical properties of materials, stress-strain diagrams, elasticity and toughness, and describe other material properties like hardness, creep strength, and fatigue strength.

9m 39s

Mechanical Engineering

Today we continue our tour through the major fields of engineering with a look at mechanical engineering, beginning with the steam engine. We’ll discuss aircraft, the development of aerospace engineering, and take a look into the future of robotics and biomechanics.

8m 36s

Heat Transfer

Today we’re talking about heat transfer and the different mechanisms behind it. We’ll explore conduction, the thermal conductivity of materials, convection, boundary layers, and radiation.

10m 5s

The First & Zeroth Laws of Thermodynamics

In today’s episode we’ll explore thermodynamics and some of the ways it shows up in our daily lives. We’ll learn the zeroth law of thermodynamics, what it means to reach a thermal equilibrium, and define the first law of thermodynamics. We’ll also explore how stationary, adiabatic, and isochoric processes can make our lives as engineers a little easier.

9m 26s

Fluid Flow & Equipment

Today we’ll dive further into fluid flow and how we can use equipment to apply our skills. We explain Bernoulli’s Principle and the relationship between speed and pressure in certain flowing fluids. We’ll also discuss how to apply the principle with Bernoulli’s Equation and try to use it in real-world examples.

11m 5s

Reversibility & Irreversibility

How do we design the most efficient machines and processes? Today we’ll try to figure that out as we discuss heat & work, reversibility & irreversibility, and how to use efficiency to measure a system.

10m 43s

Heat Engines, Refrigerators, and Cycles

Cycles are a big deal in engineering. Today we’ll explain what they are and how they’re used in heat engines, refrigerators, and heat pumps. We’ll also discuss phase diagrams and the power of using renewable energy resources.

9m 30s

The Law of Conservation

Today Shini explains the law of conservation, beginning with simple, steady-state systems. We’ll discuss conversion and yield, accumulation, and how generation and consumption can affect how much accumulation there is in a system.

9m 10s

Stress, Strain & Quicksand

Today we’re talking all about fluid mechanics! We’ll look at different scales that we work with as engineers, mass and energy transfers, the no-slip condition, stress and strain, Newton’s law of viscosity, Reynold’s number, and more!

11m 16s

Mass Separation

Engineers use three processes to separate chemicals: distillation, which separates substances based on their different boiling points; liquid-liquid extraction, which uses differences in solubility to transfer a contaminant into a solvent; and reverse osmosis, which filters molecules from a solvent by pressurizing it through a semipermeable barrier.

10m 26s

Biomedical & Industrial Engineering

We’ve discussed the four main branches of engineering but there are so many other fields doing important work, so today we’re going to explore a few of them. In this episode we’ll explore some of the history and fundamentals of industrial engineering, biomedical engineering, and bioengineering.

12m 21s

Why We Can't Invent a Perfect Engine

We’ve introduced the 0th and 1st laws of thermodynamics, so now it’s time to move on to the second law and how we came to understand it. We’ll explain the differences between the first and second law, and we’ll talk about the Carnot cycle and why we can never design a perfectly efficient engine.

8m 23s

Drugs, Dyes, and Mass Transfer

Today we’re talking about mass transfer. It doesn’t just apply to objects and fluids as a whole, but also to the individual molecules and components that make them up. We’ll see that transfers of mass need their own driving force, discuss diffusion, and use Fick’s Law to help us model mass transfer.

9m 0s

The History of Chemical Engineering

Today we’ll cover the fourth and final of our core disciplines of engineering: chemical engineering. We’ll talk about its history and evolution going from soda ash competitions to oil refineries and renewable energies. We’ll also discuss some newer and emerging fields like biotechnology and pharmaceuticals.

10m 38s

How Not to Set Your Pizza on Fire

Today we’re going to explain how exchangers...exchange heat. We’ll look at concentric tubes, finned tubes, plate heat exchangers, and shell-and-tube heat exchangers. And we’ll look at some equations to help us sort through heat transfer and decide what heat exchangers are best suited for our designs.

8m 46s

Civil Engineering

We’re beginning our engineering journey with a tour through the major branches. Today Shini explains the facets of civil engineering, including structural and construction engineering, city planning, transportation, and sanitation.

9m 37s

What is Engineering?

In our first episode of Crash Course Engineering, Shini explains what engineering is, and gives a brief overview of its four main branches (civil, mechanical, electrical, and chemical) as well as a look at some of the other fields of engineering.
