Title          
Structural Collapse: the classic case -Tacoma... 
   
 
Abstract    

The collapse of the bridge was recorded on film by Barney Elliott, owner of a local camera shop, and shows Leonard Coatsworth leaving the bridge after exiting his car. In 1998, The Tacoma Narrows Bridge Collapse was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant." This footage is still shown to engineering, architecture, and physics students as a cautionary tale.[9] Elliot's original films of the construction and collapse of the bridge were shot on 16mm

Title          
Crosswind Landing of Airbus 380 
   
 
Abstract    

A crosswind is any wind that is blowing perpendicular to a line of travel, or perpendicular to a direction. For example, in aviation, a crosswind is the component of wind which is blowing 90 degrees to the runway, making a landing more difficult than if the wind were blowing straight down the runway. In fact if a crosswind is strong enough it may exceed an aircraft's crosswind limit, and attempting to land under such conditions could cause structural damage to the aircraft's undercarriage.

Crosswinds can also occur when traveling on road, especially on large bridges and highways, which can be dangerous for motorists because of possi...

Title          
The Overtone Series 
   
 
Abstract    

An overtone is a natural resonance of a system. Systems described by overtones are often sound systems, for example, blown pipes or plucked strings. If such a system is excited, a number of tones may be produced along with the fundamental tone. In simple cases, such as for most musical instruments, the frequencies of these tones are the same as (or close to) the harmonics (integer multiples of the fundamental frequency). An example for an exception is a circular drum, whose first overtone is 2.4 times its fundamental resonance frequency. The human vocal tract is able to produce a highly variable structure of overtones, called formants, which define different

Title          
Flow Visualization: Aerodynamics of Truck vs.... 
   
 
Abstract    

A video showing the flow of dye over and through a Nascar and Truck illustrating fluid mechanics and aerodynamics. In fluid dynamics it is critically important to see the patterns produced by flowing fluids, in order to understand them. We can appreciate this on several levels: Most fluids (air, water, etc.) are transparent, thus their flow patterns are invisible to us without some special methods to make them visible.On another level, we know the governing equations of fluid motion (the Navier-Stokes equations), but they are nonlinear partial differential equations with very few general solutions of practical utility. We can solve them numerically with modern computer methods, but these solutions may not correspond to ...
