Basically they are built for useful ways to span rivers, gorges and other obstacles, Engineers can now decide which style or material is most effective and economical for the support needed for the traffic they expect. The builders must study the land carefully and decide whether a suspension bridge, a concrete bridge, whether iron, steel, girders or new metals will stand the stresses and strains. Trial and error models are made first. Using the diagrams in this book, you might like to try to make some of your own and see how they will withstand the force you apply to them. 72 Pgs.
