Mock Lectures

Our professors are excited to provide lectures to middle and high school students on a wide variety topics with the hopes of not only imparting new knowledge, but to also get more youth excited about engineering careers. Use the menu below to view topics currently being offered. Don't see what you're looking for? Let us know and we'll see what we can put together for you. Lectures can be made available in person as classroom visits, or online. 

Why are they called, "Mock Lectures?" Because these topics are all slightly adapted content from actual lectures these professors use in their classes. We hope students don't just learn something new, but also experience a sample of what the college experience can and will look like for them some day!

Discipline: Mechanical Engineering
Grades: 9-12
Duration: 20-40 minutes
Presenter: Dr. Jennifer Brock, Associate Dean for Academics and Mechanical Engineering Professor

Abstract: The lecture focuses on the history of the idea of the sound barrier: where did the idea come from, why did people believe that it couldn鈥檛 be broken, who were these people who believed it couldn鈥檛 be broken, etc.  It lays out the science for why fluid dynamics at extremely high speeds is a more complex mathematical problem than fluid dynamics at lower speeds.  It also goes through the surprising history of compressible fluid dynamics, which reveals that the science was actually pretty well-established in a lot of ways before the start of the twentieth century.

Material Selection in Mechanical Engineering

brakes 

Discipline: Mechanical Engineering
Grades: 9-12
Duration: 45 minutes
Presenter: Dr. Matt Cullin, Mechanical Engineering Professor

Abstract: This lecture explores the material selection portion of the engineering design process. Automotive brake rotors are used as an illustrative example of the interplay between geometry, material selection, and performance of a mechanical component. Students are introduced to the physical properties of four classes of engineering materials: metals, ceramics, polymers, and composites. Common brake rotor designs are examined to illustrate the tradeoffs between cost, performance, and reliability that are commonly encountered in engineering practice.

鈥淧hase鈥 Book: Graphical Map of Water Systems

Water systems graph 

Discipline: Mechanical Engineering
Grades: 6-12
Duration: 30-45 minutes
Presenter: Dr. Raghu Srinivasan, Assistant Professor, Mechanical Engineering

Abstract: Different phases exist for material systems and phase diagrams or equilibrium diagrams helps you identify the stable phases present based on temperature and pressure (similar to finding a location on a map based on coordinates). A phase is some portion of a body of materials throughout which the physical and chemical characteristics are homogenous. For example, water system has three phases: Ice (solid), Water (Liquid), and Steam (vapor). This lecture details the importance of pressure when mentioning the boiling point or melting point of water. This lecture will also introduce the phase concepts in metal systems.

Rust and Rot: Corrosion Chemistry

Discipline: Mechanical Engineering
Grades: 6-12
Duration: 30-45 minutes
Presenter: Dr. Raghu Srinivasan, Assistant Professor, Mechanical Engineering

Abstract: What is the difference between rust and corrosion? Why doesn't gold corrode? This lecture talks about corrosion and how it affects every one of us. Corrosion is ubiquitous and it is defined as the degradation of metals when exposed to a corrosive environment. Atmospheric corrosion is surely the most visible of all corrosion processes and you can see that in rusty bridges, flag poles, buildings, cars, ships and outdoor monuments.

Strength Vs Toughness: Impact Testing of Metals

pendulum 

Discipline: Mechanical Engineering
Grades: 6-12
Duration: 30-45 minutes
Presenter: Dr. Raghu Srinivasan, Assistant Professor, Mechanical Engineering

Abstract: Have you ever seen a heavy hammer swing like a pendulum? A hammer is dropped on to steel specimens at different temperatures to qualitatively determine their impact toughness. Most metals go through elastic deformation under applied force (very small though). This is very similar to a rubber band where they can be expanded under force and restored to its original shape once the applied force is removed. This phenomenon in metals is not apparent visibly like the rubber band. Once the applied force exceeds a certain value, metal changes its shape permanently (cannot be restored to its original shape after the force is removed) and this phenomenon is called plastic deformation. Most metals eventually fail after going through elastic and plastic deformation and we call this as ductile fracture. Some metals fracture right after elastic deformation without any plastic deformation (similar to glass rods) and we call this as brittle fracture. There are few metals that go through this transition from ductile to brittle fracture as the temperature decreases. This Charpy Impact test will show the fracture of steel specimens at different temperatures and how it absorbs the energy when the hammer is dropped from a pendulum.
