Description
Do-It-Yourself Engineering Course. Everyone appreciates a well-designed bridge, a sturdy skyscraper, or a flight-capable airplane. But how many of us who aren’t engineers think, “I can build that”? Actually, you can. You may not have the qualifications of a professional engineer, but you can tinker with anything you want in your workshop, using readily available materials to build working models that solve all the basic problems of reality. With a do-it-yourself spirit and an engineer’s approach to problem-solving, you can design and build small models of any structure, machine, or device in the world today. And as you tackle these projects, you’ll gain a deeper understanding of scientific and engineering principles, knowledge of basic algebra and trigonometry, and new strategies and skills for use in the workshop—all while having a lot of fun! So roll up your sleeves and get started with Do-It-Yourself Engineering, 17 cool DIY projects in 24 half-hour lessons. – From ancient catapults to modern flying machines, from motorized cranes to mechanical clocks. Some of the most amazing projects you will experience include:
- Suspension Bridge: An eight-foot-tall suspension bridge requires two towers approximately five feet tall. By calculating the loads the structural system will experience when fully loaded with pedestrians, you can design and build a lightweight and stable bridge using readily available hardware.
- Skyscraper: An ideal introduction to structural engineering, a tower structure made from just a few sheets of cardboard that can be transformed into sturdy columns, beams and bracing. A properly constructed tower three feet tall can support more than 100 pounds of bricks stacked on top of each other!
- Airplanes: The Wright brothers built a wind tunnel to develop the design of their airplane wings. You can also use a regular fan at home. Your model airplane will also need a propulsion system, three-axis stability, and a way to control its flight path – problems you can solve using basic aerodynamic theory.
Your instructor is award-winning teacher Stephen Ressler, DIY enthusiast and professor emeritus of the United States Military Academy at West Point, and a long-time favorite of great courses. Step-by-Step Instructions: Professor Ressler walks you through every step of each project, describing the design process, walking through the construction steps on camera, and illustrating them with detailed drawings of his own. It shows real 3D computer models. The attached course guide contains all the mathematical calculations needed for each design, step-by-step construction instructions, a complete list of materials and tools, and a set of full-size sewing patterns you can print out to cut the pieces. . In addition, you can download your own copies of the 3D computer models and other resources from the course website. This course will appeal not only to those who want to build challenging projects, but also to those who want to learn to think like an engineer or enjoy watching a master craftsman at work. Professor Ressler uses high school level algebra and trigonometry throughout the course, which he explains as the course progresses, so even those whose math skills are rusty have the tools to fully enjoy each step of the process. , “Do-It-Yourself Engineering” was recorded in The Great Courses studio in a simple benchtop workshop equipped with standard power tools. Professor Ressler breaks each project down into three phases:
- Design: This is where Dr. Ressler defines the problem and often examines several possible solutions. He then selects one, develops it in detail, and sketches the evolving concept on the whiteboard. This is where the math and physical principles like the law of conservation of energy come into play. These principles allow you to predict the performance of the device even before it is built.
- Construction: Many DIYers start here with trial and error, which results in a waste of effort and materials. As you will learn in this course, you must first have a fully developed plan. During the construction phase, Professor Ressler will show you how to use power and hand tools at each step, with an emphasis on safety. He is the shop’s primary instructor in these areas of instruction.
- Experimentation: This is the moment of truth and sometimes an opportunity for creative troubleshooting to solve problems. For yachts, hot air balloons, airplanes, helicopters and rockets, this is an opportunity to fine-tune to prepare the vehicle for the next mission. For two bridges, it ensures the structure is safe for pedestrian traffic. For three catapults, it means it’s time to start the fight!
Learn by doing: Build! Invent! Create! These are some of the culture-building slogans that are revolutionizing education by focusing on exploration, self-reliance, and the joy of creating. Do-it-yourself engineering fits right into this vision. About 2400 years ago, Aristotle wrote, “We learn by doing.” It’s still true today that anyone can buy a fully functioning model airplane on the Internet, but by designing and building one from scratch, you learn what makes an airplane fly. How it climbs, falls, and turns. What keeps it stable? And what causes the dangerous phenomenon called stall? Your other learning adventures in this course include:
- Buoyancy: Buoyancy is the force that makes boats float – even those made of concrete. Also, the reason the cushion rises is filled with helium. In either case, you can use math to calculate the size of your ship to make sure the buoyancy force will support the weight of the model.
- Torque: The rotational force known as torque plays a prominent role in the design of many technical systems. In your model helicopter, the significant torque generated by the main rotor must be balanced by a tail rotor. Changing the torque with the gearbox is one way to optimize the performance of a water turbine. Gear trains are also very important in the operation of pendulum clocks and motor cranes.
- Electricity: One of the exciting projects you will experience is a model rocket. An electric launch controller is not attractive when the engine ignition is low. Since safety is paramount, design a circuit with safety features. Along the way, you will learn about voltage, current, resistance, batteries, and soldering. Then launch!
The U.S. Military Academy at West Point, where Professor Ressler taught for 21 years before retiring, is known for the quality of its engineering programs. After immersing yourself in these 24 delightful and insightful lessons, you will have no doubt that Dr. Ressler’s teaching is not only challenging, but also wonderfully clear and immensely fun. Among his many talents is the timing of a demonstration, as he unforgettably demonstrates in the final lesson, a DIY engineering conclusion that is second to none.
