Tunnel Engineering 30:17 minutes
Delve into tunnel engineering, a discipline every bit as impressive as bridge building, only less visible. Consider the challenges presented by the type of soil or rock being excavated for a tunnel, marvel at the work of mammoth tunnel boring machines, and weigh the tradeoffs between tunnels versus bridges.
The Railroad 31:39 minutes
Ride the rails to learn why rail transportation continues to thrive, two centuries after the modern railroad was introduced. Trace the origin of the standard rail gauge used in the U.S., probe the forces a locomotive must overcome to get rolling and then stop, and chart the rise of a revolutionary way of handling cargo: the intermodal container.
By the end of this course the student will be able to summarize the challenges presented by the type of soil or rock being excavated for a tunnel, marvel at the work of mammoth tunnel boring machines, and weigh the tradeoffs between tunnels versus bridges, and understand the origin of the standard rail gauge used in the U.S., and identify the forces a locomotive must overcome to get rolling and then stop, and chart the rise of a revolutionary way of handling cargo.
