A falling weight deflectometer, towed by a truck. A falling weight deflectometer (FWD) is a testing device used by civil engineers to evaluate the physical properties of pavement in highways, local roads, airport pavements, harbor areas, railway tracks and elsewhere. The data acquired from FWDs is primarily used to estimate pavement structural ...

Joule's apparatus for measuring the mechanical equivalent of heat in which the "work" of the falling weight is converted into the "heat" of agitation in the water. Benjamin Thompson, Count Rumford, had observed the frictional heat generated by boring cannon at the arsenal in Munich, Bavaria, circa 1797. Rumford immersed a cannon barrel in water ...
The author of the new report (not free) says "Readers are cautioned not to rely on or in the future refer to numbers from the 2007-08 Insight SRI paper The Economic Cost of FOD to Airlines. This earlier effort was 'The' first document detailing the direct and indirect cost of FOD that was based on airline maintenance data (the entire document ...
