This collection of undergraduate Engineering Statics analyses and solutions constitutes an Engineering Lecture Complement (ELC). It is a tool made possible by Internet technology and can be used to increase classroom productivity, teaching flexibility and personalized learning.
This computer oriented, WEB based presentation is not an engineering text in the traditional sense. Important fundamental definitions, concepts, and derivations found in many excellent texts are not repeated. Here one begins with a problem, or application, and builds upon the fundamental foundation as needed. This simulates the manner in which most engineering problems are addressed in practice. If this material is used to support an introductory course in college, the instructor should assure that the student is aware of all assumptions, limitations, and abstractions inherent in the mathematical definitions and theory. If this material is used by practicing engineers or graduate students, they should be aware of suitable references that can be used as needed to justify the selected approach to a problem.
This material is suitable for a new national priority, e.g., the computer supported and Internet based instruction of engineering courses. Building on an assumed background in calculus and physics, 3-D Vector Analysis is first presented along with 3-D interactive graphics using Mathcad surface plotting capability. This allows the user to reason spatially and visualize in three dimensions.
The collection of problems in each chapter follows the normal sequence found in most sophomore level textbooks in engineering mechanics. Two dimensional equilibrium is followed by the static analysis of truses and frames. Then follows the computational techniques suitable for the analysis of three dimensional equilibrium.
