ABSTRACT
Engineering is the application of mathematics and science to build structures and machines. It includes subcategories such as architectural, chemical, civil, computer, electrical and mechanical, for example. This chapter will concentrate on electrical and mechanical engineering only. Electrical engineering is concerned with devices and systems which use electricity, electrons, and electromagnetism. Mechanical engineering is the study of objects and systems in motion. The first section is on linear electrical circuits composed of resistors, inductors, capacitors and voltage sources and introduces a fourth fundamental component, called the memristor, which was discovered in 1970, and first built in 2008. The second section introduces the reader to Chua's nonlinear electrical circuit, and a program for producing an animation is listed. The third and fourth sections cover mechanical engineering with simple examples of coupled oscillators and periodically forced mechanical systems, respectively.
