Hoe Knife

A hoe weighing 8 tons is on top of a flatbed trailer and heading east on Interstate 70 near Hays, Kansas. The extended shovel arm is made of hardened refined steel and the approaching overpass is made of commercial-grade concrete, reinforced with 1 1/2 inch steel rebar spaced at 6 inch intervals in a criss-cross pattern layered at 1 foot vertical spacing.

Solve: When the shovel arm hits the overpass, how fast do you have to be going to slice the bridge in half? (Assume no effect for headwind and no braking by the driver.)

Photographs displayed above capture the aftermath of an accident that occurred on the evening of February 13, 2006 on Interstate 70 near Hays, Kansas. The driver of a semi-tractor trailer that was hauling a track hoe excavator on a flatbed misestimated the clearance at an overpass, and the boom of the hoe collided with the overpass and knocked a 45-foot gap through the deck of the bridge. The accident forced an 11-day closure of the eastbound lanes of Interstate 70. (The bridge itself remained closed even after the highway reopened.)

The driver of the rig was uninjured, although he was later cited for not having clearance to drive on the interstate. The Kansas Department of Transportation said the construction company for which the driver worked would be liable for the cost of repairs to the overpass, which were estimated at $134,000 as of late March 2006.

Press release

Lamborghini is redefining the future of the super sports car with a unique technology demonstrator. Boasting an extremely lightweight construction thanks to advanced carbon-fiber technology, the Lamborghini Sesto Elemento has an overall curb weight of just 999 kilograms (2,202 lb) – including V10 power unit and permanent all-wheel drive. This makes the Sesto Elemento a unique demonstration of the technological expertise of Automobili Lamborghini. Innovative carbon-fiber technologies are being used here for the first time in an automotive application. As a 100 percent subsidiary of AUDI AG, the Italian carmaker also benefits from the undisputed expertise of the German manufacturer when it comes to lightweight construction.

With its amazing output of 570 hp, sensational power-to-weight ratio of only 1.75 kilograms per hp and 0 to 100 km/h (0-62 mph) acceleration of only 2.5 seconds, the Sesto Elemento guarantees unparalleled driving fun. At the same time, fuel consumption also drops because of the extreme lightweight engineering applied throughout.

The name of this technology demonstrator is derived from the periodic table, where carbon is classified as the sixth element. Thus, the Sesto Elemento demonstrates the worldwide leading expertise of Lamborghini in carbon-fiber reinforced plastics (CFRP) technology. The super sports car brand from Sant’Agata Bolognese is the only vehicle manufacturer in the world to have mastered the complete CFRP process across a range of technologies, from 3D design through simulation, validation, production and testing – all in a state-of-the-art industrial process that stands for the very highest quality standards.

Lamborghini drives the technology development in its two research centers the ACRC (Advanced Composite Research Center) and the ACSL (Advanced Composite Structures Laboratory) through collaborations with organizations such as Boeing, with the resulting technology secured under a host of patents.

“The Lamborghini Sesto Elemento shows how the future of the super sports car can look – extreme lightweight engineering, combined with extreme performance results in extreme driving fun. We put all of our technological competence into one stunning form to create the Sesto Elemento,” comments Stephan Winkelmann, President and CEO of Automobili Lamborghini. “It is our abilities in carbon-fiber technology that have facilitated such a forward-thinking concept, and we of course also benefit from the undisputed lightweight expertise of AUDI AG. Systematic lightweight engineering is crucial for future super sports cars: for the most dynamic performance, as well as for low emissions. We will apply this technological advantage right across our model range. Every future Lamborghini will be touched by the spirit of the Sesto Elemento.”
