* MENG 320a / ENRG 320a / ENVE 320a, Energy, Engines, and ClimateAlessandro Gomez

The course aims to cover the fundamentals of a field that is central to the future of the world. The field is rapidly evolving and, although an effort will be made to keep abreast of the latest developments, the course emphasis is on timeless fundamentals, especially from a physics perspective. Topics under consideration include: key concepts of climate change as a result of global warming, which is the primary motivator of a shift in energy supply and technologies to wean humanity off fossil fuels; carbon-free energy sources, with primary focus on solar, wind and associated needs for energy storage and grid upgrade; and, traditional power plants and engines using fossil fuels, that are currently involved in 85% of energy conversion worldwide and will remain dominant for at least a few decades. Elements of thermodynamics are covered throughout the course as needed, including the definition of various forms of energy, work and heat as energy transfer, the principle of conservation of energy, first law and second law, and rudiments of heat engines. We conclude with some considerations on energy policy and with the "big picture" on how to tackle future energy needs. The course is designed for juniors and seniors in science and engineering.

* MENG 325a, Machine Elements and Manufacturing ProcessesJoran Booth

This course provides students a working knowledge of two fundamental topics related to mechanical design: machine elements and manufacturing processes. Machine elements refer one or more of a range of common design elements that transmit power and enable smooth and efficient motion in mechanical systems with moving parts. This course introduces the most common of these elements and gives students the tools to systems design with them. Topics include common linkages, gearing, bearings, springs, clutches, brakes, and common actuators such as DC motors. Manufacturing processes are necessary for the mechanical design engineer to effectively perform her or his duties; they provide an understanding of how the parts and systems that they design are fabricated, allowing “Design for Manufacturing” principles to be taken into account in the product development process. Students learn the basics of common commercial manufacturing processes for mechanical systems, including low-volume processes such as machining to high-volume processes such as casting (metal parts), molding (plastic parts), and stamping (sheet metal parts).    Prerequisites: Extensive CAD experience.

MENG 425b, Advanced Design and Analysis of MachinesRonald Adrezin

There are many useful, classic mechanisms that require a single actuator to operate.  These include four-bar mechanisms, slider-cranks, cam-followers, and scotch-yokes. In this course, students learn to design (synthesize) classic mechanisms. They also learn how to analyze the kinematics and kinetics of important machines. While systems based on single actuators are common, the course then introduces the dynamics of multiple degree-of-freedom machines such as robotic actuators. This course focuses on planar systems and students learn to write equations of motion of robots that can roll forward with multiple articulating linkages. Students design and analyze using SolidWorks and solve equations with Matlab. A project is designed, analyzed, built, and tested utilizing a microcontroller and 3D printer.

Special topic lectures focus on recent developments in the field of robotics and highlight core research areas. A final class project takes place instead of a final exam where students leverage the codebase they have built throughout the course in a robot problem of their choosing. Experience with differential equations, linear algebra, and basic understanding of dynamics is required. Basic coding experience in e.g., python, c++, c, are also required.
