Arc-Fault Circuit Interrupters (AFCIs)

What is an Arc-Fault Circuit Interrupter (AFCI) and how does it work? AFCIs are microprocessor-controlled devices that continuously monitor the voltage and current flowing in a circuit and interrupt the current flow if an arc is detected, and have been required as part of the National Electrical...

Pigs may not fly yet, but COW’s do!

Beyond the obvious engineering applications or the occasional mention of a pizza or package delivery that most of us continually hear about, what sort of crazy, perhaps brilliant, drone applications have industrious problems solvers come up with? The following are three of my favorites.

Condensate Drainage

To understand proper condensate removal, it is first important to have a working definition of the term condensate in the context of Heating, Ventilation, and Air Conditioning (HVAC). Most HVAC systems contain a form of refrigeration cycle which uses mechanical work acting on a fluid (in most cases...

Snow Loads

EDT

Freshly fallen snow is often a beautiful and awe-inspiring sight to see. Some parts of the country may see new snow daily while other areas may only see it once a century. Regardless of how prepared our cities are, snow can have a great impact on our everyday lives, particularly on our structures...

Fractures (part 1)

Our Scanning Electron Microscope (SEM) is capable of 100,000X magnification, allowing a close-up look at material surfaces for defects, inclusions, and fracture characteristics. By using a SEM/EDS to study the surface of the fracture, the question of how the part broke - or the mode of fracture -...

Computer Graphics

EDT

Computer graphics are visual communication tools to aid an audience in visualizing data in a clear and interesting manner, compared to text or oral communication alone. Within this article are examples of how EDT uses Computer Graphics for Forensic Engineering purposes.

Food Processing Facility Construction Defect

Charles E. Whitley, P.E.

EDT was asked to review the construction of a multimillion-dollar addition to a food processing facility and to determine the cause of water penetration through the floors of the facility. The following information is a review of what we found that went wrong, and what we concluded to "solve" this...

Star Bolts

Have you ever noticed eye-catching stars positioned on the fronts of masonry row homes in urban areas, such as Philadelphia, New York, Baltimore, and various other cities? The stars are not just ornamental; they are also functional.
