From intro The desire by people to travel about was one of the earliest incentives to build bridges. Trade and transport of goods were soon to follow. Early bridges date to the days before Christ. Early bridge builders used large flat rocks laid on stones in the river and trees felled singly or together. During the Roman era developments were made in bridge building techniques using stone and an early form of concrete to make circular arches. Simple trusses were constructed in this pe-riod. Made of wood, these trusses could span 20-60 feet. These simple designs are still common today. The advent of the railroad brought a sudden mand for bridges. Developments in bridge design id construction progressed simultaneously in Europe nd in the United States. In Europe, the main efforts vere focused on the development of the metal girder nd design of the arch. In the United States, however, nterest focused on the development of the truss, first n wood, later in iron, and finally in steel. It was only natural that with the wealth of timber the United States would develop principles suitable to design with wood. The truss is one of the major types of engineering structures today. Generally, the truss is made by forming triangles with members which are joined at the intersections with a connection (a joint). Loads applied to the truss are carried along members. Trusses are used in many applications. They can be spotted when house roofs are being constructed, in towers that support power lines, as well as in bridges. Trusses may be small or they can be large. Simple, small trusses were used initially. As longer spans were needed, more complicated trusses came into use. What makes simple trusses fun is that they can be understood using simple principles of math and engineering. This book explains these simple principles in a fun way. These principles are the foundation of Civil Engineering and other fields of engineering. Much of engineering can be intuitive as it is the study of the constructed features around us all of the time. In the following chapters examples and drawings are used to help visualize the principles discussed. Bridges are used to make the explanations but watch for trusses all around you.
