How Was That Built?
80pp., hbk., RRP $A29.99
From the time our earliest ancestors sought shelter in caves and discovered their limitations, humans have been building structures, each seemingly grander than its predecessors as challenges such as height, length, shape, and strength are overcome and physical impediments such as being underwater, underground, on ice and even in space are conquered.
There is something comfortable and comforting in being enclosed -perhaps it stems from the confines of the womb – and from the early childhood days of making a cubby with a sheet over chairs (itself having evolved to purchased indoor tents) to building towers from toothpicks and peas to bridges “strong enough to hold a toy car” from paper, our junior engineers have evolved to become those making the creations that dominate the modern landscape. While some, like the pyramids , Stonehenge and other ancient temples have endured across centuries, this book focuses on more modern structures which have solved the problems like how to build high, long, strong and so forth, explaining with explanations and illustrations how the obstacle has been overcome in both general and specific circumstances.
For example, in the section How to Build Across, the mechanics and physics of various bridge designs are demonstrated and then the construction of Te Matau Ā Pohe, a bridge across the Hatea River at Whangarei, New Zealand that needs to be able to lift quickly to allow essential boat traffic to pass, is explored, showing how the engineers drew on the Māori legend of Maui fishing the North Island from the sea with his hen matai, a magical fish hook, to create the lift mechanism.
Although more for those in Year 5/6+, this is an intriguing book for readers who want to take the basic “design, make, appraise” of STEM to its next level or who have a fascination with structures and aspirations to be structural engineers themselves. For those just intrigued by big buildings, it is equally fascinating as they learn the whys, whats and hows of their favourites.
