Towers and Bridges - Making Ends Meet - delves into the science behind the construction at a level which teenage readers can appreciate and be challenged by. Lavishly illustrated with photographs and diagrams, the book was written by teachers specifically for students at upper primary and lower high school level. It has been trialed in the classroom for several years with great success. Now, completely updated, it's ready to educate students on how civil engineers can span wider gorges and rivers with bridges, and reach new heights with towers and skyscrapers. These essential structures allow us to access towns and cities easily, and to communicate across the globe using radio transmissions from tall structures. Engineers build bridges over rivers, lakes, canyons, highways and railways so we do not have to cross them with boats or travel around them. Towers are built to gain height for radio antennas, lookouts, lighthouses, wind turbines and for many other reasons. They have become an integral part of the society in which we live today. Read about famous towers and bridges, construction challenges, the basic bridge types, design techniques, specialist bridges and towers, and how engineers profit from mistakes. The book includes an extensive illustrated glossary and a thorough index.
