Great resource website for engineers

Here is a website - eFunda - that is a great information resource for engineers and engineering students in all disciplines. The website explains itself as:

"eFunda stands for engineering Fundamentals. Its mission is to create an online destination for the engineering community, where working professionals can quickly find concise and reliable information to meet the majority of their daily reference needs.

eFunda is all about the basics, for most part, that means college level material covered in engineering schools. If you practice engineering, more often than not you would find yourself searching for something you knew but could not quite remember. eFunda wants to be your reminder of these formulas. Not only that, eFunda wants to tell you exactly under what conditions those formulas apply, so you don't have to read an entire chapter of the good old textbook."

The following sections of the website include these sub-sections:

Materials

• periodic table
• steels
• aluminum
• polymers
• etc.

Design Center

• plastic design
• gages
• springs
• o-rings
• etc.

Processes

• casting
• stamping
• molding
• annealing
• etc.

Unit Conversion

• length
• mass
• pressure
• time
• etc.

Formulas

• beam
• plate
• composite
• vibration
• etc.

Mathematics

• areas
• trigonometry
• Taylor Series
• least squares
• etc.

Explanations are simple, concise and focused. This is not only useful for students' knowledge (or refreshing of knowledge), but also a good example of straightforward explanation.

Other sections of the website include a Forum, where various technical questions are discussed; Magazines for free in a wide variety of engineering and technical areas; and Calculators, which has conversions of all kinds.

All in all, a great resource for engineers, engineering students and teachers of engineering disciplines.
