The Bridge Designer is a web-based program that allows the user to design and analyze 2-Dimensional statically determinate trusses. The user can specify support types (fixed or rolling) and locations, as well as the locations of various truss nodes and members.

eCourses web portal is designed to assist both students and professors in basic engineering courses. The web site includes all instructional material to conduct a course and there is no cost to either the instructor or student. Features include eBook, database of homework/quiz/test problems, solutions to all problems, lectures in both Quicktime and Flash format, computer grading, and utilities. To help facilitate communications between students, instructors, and TAs there is an integrate web board and collaborative drawing board. Each web-based course is controlled and administered by the instructor. There are six complete engineering eBooks available directly without having to register or set up any class. The eBooks cover Statics, Dynamics, Thermodynamics, Fluids, Math, and Multimedia. The eBooks are also searchable using a Google-Mini for fast and accurate indexing.

The NSDL was created by NSF to provide organized access to high quality resources and tools that support innovations in teaching and learning at all levels of science, technology, engineering, and mathematics (STEM) education.

What is a vector? The answer may surprize you. But let's start with the simplest view of a vector. It is an arrow that records distance and direction. By stringing together a sequence of arrows we can provide detailed directions for a journey, or outline an object. It is the way we add arrows to produce a new arrow that really identifies what a vector is. We can incorporate this addition property to other quantities such as velocities, forces, and even functions. What quickly emerges is that it is the linear combination of vectors that allows great diversity in applications and provides deep understanding to the nature of solutions to linear problems. This module starts with the basic Description of vectors and then proceeds to elucidate their role in the Formation of systems of linear equations.

The Probability and Statistics EBook is an internet-based electronic textbook. The materials, tools, and demonstrations presented in this EBook would be very useful for advanced-placement (AP) statistics educational curriculum. The EBook was initially developed by the UCLA Statistics Online Computational Resource (SOCR). However, all statistics instructors, researchers, and educators are encouraged to contribute to this project and improve the content of these learning materials. There are four novel features of this specific Statistics EBook: it is community-built; completely open-access (in terms of use and contributions); blends information technology, scientific techniques, and modern pedagogical concepts; and is multilingual.
