Ultimately, the selection of materials in structural design is a complex decision that must take into account a range of factors, including the desired strength, durability, and cost of the structure, as well as the availability of materials and the practical considerations of the construction process. For example, while a material like titanium may be very strong and lightweight, it is also expensive and not readily available in large quantities, making it less practical for certain applications. In addition to the physical properties of materials, Gordon also highlights the importance of cost and availability in materials selection. On the other hand, materials like wood are lightweight and easy to work with, but they may not be as strong or durable as other materials, and they are also more prone to fire damage.

However, they are also susceptible to corrosion and fatigue, which can weaken the structure over time. For example, he notes that metals such as steel are strong and durable, making them a popular choice for building structures like bridges and high-rise buildings. Gordon discusses the properties of various materials and their suitability for different types of structures. “Every structure has a critical size at a smaller size it would not be strong enough to support its own weight at a larger size, the ratio of surface area to volume becomes too great for its strength to support its weight.” The choice of material can have a significant impact on the strength, durability, and overall performance of a structure, and it is therefore a critical decision that must be made with care.

Gordon emphasizes the crucial role of materials selection in structural design. “Engineering is the art of organizing and directing men, and of controlling the forces and materials of nature for the benefit of the human race.” Materials Selection in Structural Design

Using a blend of historical anecdotes, scientific explanations, and real-world examples, Gordon presents a comprehensive overview of the fundamental concepts that underpin the design and construction of structures. Gordon, takes readers on a journey through the various structures that surround us, from bridges and buildings to airplanes and even living organisms. Through a series of engaging and thought-provoking discussions, the author, J.E. “Structures: Or Why Things Don’t Fall Down” is an insightful and informative book that explores the principles of engineering, materials science, and physics.
