Lecturer: Stephen Ressler, Ph.D.
Look around you lot. Great masterpieces of technology are everywhere. As soon as you go out of bed in the morn, yous are putting centuries of scientific and mechanical ingenuity to employ. So familiar are these structures, inventions, and services that they are all but invisible. Yet they are just equally remarkable as swell works such equally the Parthenon, the Eiffel Tower, and the Panama Canal.
Consider for a moment the wonders of these marvels that have likely already played an important part in your day today:
Residential construction: Congenital with common materials and simple tools, the modern business firm is a technological arrangement for living. It provides protection and condolement, access to life's necessities, and a flexible space for work and recreation.
Telecommunication: Able to link you to whatever phone in the world, the traditional phone system is miraculous enough. Even more wondrous is the array of services available through new telecommunications technologies such as cellular networks.
Transportation: You can get there from here, cheers to automotive engineering, petroleum drilling and refining, satellite navigation, and a road system that is fast, rubber, and goes nearly everywhere.
Water and power: Your house would be dark and bleak without connections to infrastructure systems that supply fresh water, dispose of wastewater, and furnish a power source-electricity-that provides illumination and animates nigh of your household appliances.
All of the states use these technologies, and knowing how they work empowers us in major ways. Anyone who owns a dwelling or is in the market for one benefits enormously from understanding how it is synthetic and how the roof, insulation, plumbing, wiring, heating, and cooling systems are integrated into the building. Anyone who'due south buying a automobile or needs to go one stock-still can residue easier knowing how spark plugs, transmissions, tires, and brakes do their jobs.
And because the development and utilise of everyday technologies-from solar cells to cell towers-are often strongly influenced by public policy, understanding everyday engineering helps us make more informed decisions about the kinds of policy initiatives we wish to support.
Plus, the achievements of everyday applied science are worth admiring for their own sake. They represent some of the well-nigh inspired thinking of our civilisation, and by looking under the hood to see how these technologies operate, yous learn about bones scientific principles that apply throughout the earth.
For these reasons and more than, Everyday Engineering: Agreement the Marvels of Daily Life is an indispensable guide to the fashion things piece of work in the globe effectually you. Conducting this centre-opening bout is Professor Stephen Ressler of the United States Armed forces Academy at West Indicate, an laurels-winning civil engineer and a nationally honored leader in applied science education.
In 36 half-hour lectures, richly illustrated with instructive concrete models, estimator animations, and graphics designed by Professor Ressler himself, you lot start past learning how a firm is put together with all its subsystems. Then yous move outside to trace the origin and route of water, ability, and telecommunications networks. Finally, yous hit the road to discover how automobiles function and how roads and highway bridges are engineered.
Forth the manner, Everyday Engineering investigates power plants, dams, aqueducts, railroads, communication satellites, home energy efficiency, simple machines around the business firm, recycling, and many other topics. No background in scientific discipline or technology is needed to follow this riveting presentation, which gives y'all deep insight into the underlying simplicity of the complex systems that raise our lives.
Come across Familiar Things with New Optics
As an case of how Professor Ressler can turn everyday devices into a fascinating lesson in creative problem solving, he devotes an entire lecture to the faucet, showing how the trouble of delivering hot and common cold h2o into a sink has elicited a host of solutions-some practical, others non. Nosotros are all familiar with automatic faucets in public restrooms that defeat our initial attempts to get them to work, or two-handled faucets that lack clues about which way to turn the knobs. Y'all'll be surprised past the subtlety of the trouble and the wide assortment of approaches, which is typical for bug of user-centered design.
Other intriguing insights you'll go from the class include:
The genius of building codes: Houses are such complex technological entities that you might retrieve an engineer would be needed to design each one. But building codes effectively serve equally a substitute for an engineer's judgment, specifying construction methods at a high level of detail.
Gone with the wind: Compared to traditional masonry and timber-framed dwellings, modern light woods frame houses are so calorie-free and sturdy that it's possible to imagine i being lifted from its foundation by the wind and transported intact far away-as happened in the archetype 1939 movie The Magician of Oz!
Relieve money and get green: Professor Ressler has plenty of advice for enhancing the energy efficiency of your home. People in the marketplace for a new home should know about the latest trend in efficiency: the cyberspace-null-free energy house. Thank you to passive-solar design and in-abode renewable energy sources, it requires no cyberspace input of energy over the course of a year.
Talking torque: The primal to agreement how power is transmitted from an engine to the wheels of a automobile is the concept of torque-the tendency of a force to cause rotation-which helps explicate power, acceleration, speed, fuel economy, and why internal combustion vehicles require multiple gears.
A Field Guide to Everyday Applied science
Professor Ressler notes that his approach to Everyday Engineering is inspired by a very familiar genre: "Many people, myself included, find great satisfaction in identifying stars in the night sky, in distinguishing a red-tailed hawk from a turkey vulture," he says. "The technological earth is certainly no less interesting, simply lacks the guidebooks available to stargazers and birdwatchers. I hope this course will provide just such a resource by serving as a sort of field guide to everyday technology."
With this outlook and the enlightening data in these lectures, y'all will be able to expect at the earth effectually you and decipher mysteries such every bit these:
The unassuming utility pole: Next time yous're stuck in traffic, savor the complexity of the common utility pole, which typically has three high-voltage ability distribution feeders, 3 insulators, and a neutral wire; and might as well carry transformers, excursion breakers, depression-voltage distribution lines, and telecommunications cables.
Ballet of the bulldozers, scrapers, and dump trucks: Ever wonder why so many kinds of earthmoving machines are needed at a highway construction site? They're following precisely choreographed instructions on a mass diagram, with each blazon of vehicle moving soil according to its optimum operating range.
The ability outage puzzle: Sometimes electrical ability goes out and and then seconds afterward returns. What's usually happening is that a specialized circuit breaker, called a recloser, has tripped in response to a short circuit, such every bit a tree falling on a power line. The device automatically restores power if the fault has cleared.
Mystery of the missing web page: Web pages can get stuck in the process of loading, while you stare at the spinning wait cursor on the screen. The trouble is commonly heavy Internet traffic, which exceeds the storage capacity of a router somewhere in the network. The overflow packets of data that comprise the web page are sometimes but lost.
Ane of the pleasures of Everyday Engineering is the meticulous care that Dr. Ressler has taken in preparing over 150 working models that explain everything from an curvation dam to the universal joint in a motorcar'southward drive shaft. He as well delights in the unexpected: in the concluding lecture he switches gears past examining a famous case when engineering failed during the Great Northeast Blackout of 2003. Triggered by high electrical demand during a sweltering summer solar day, a short circuit due to overgrown trees, and a software problems that disabled a control room alert organization, the cascading series of breakdowns produced the worst-ever electrical power blackout in Northward America.
This incident serves every bit a graduation do for the class. Having explored the workings of the electrical power grid in previous lectures, you'll observe that you empathize the crisis in perfect particular. Indeed, you'll be ready to apply your broad agreement of everyday engineering to any technological issue that crosses your path in the future.
