This video explains why ridges move, and other musings on thermal movement of large civil works. Most people have a certain intuition about thermal expansion, but you may not have considered how engineers design to accommodate it on large civil structures. The video gives a quick overview on this important consideration that engineers must account for when designing infrastructure like pipelines, bridges, and even sidewalks.
These tutorials cover a range of material that, depending on where you go to school, might show up in either mechanics of materials 2 or structural analysis courses. A solid understanding of mechanics of materials is necessary to understand the topics presented here.
