I fully agree with the reliability and handling of racecars. What good is a racecar if it breaks (fails) before the end of the race? I've seen many interviews from top competitive drivers sorely disappointed in their provided equipment that broke just before the race ended. Racecars that can't handle well look slow on the race tracks compared to the better handling cars, and that very much includes NASCAR. Tires and suspension adjustments are critical to success (tires can be adjusted by air pressure).
The comment about the aerodynamic vacuum under these cars at speed reminded me of the Chaparral 2J car from the Can-Am series in the 70's. The car has side skirts and an on-board "vacuum cleaner' powered by a snowmobile engine which generated a downforce which exceeded the weight of the car. It was so much faster than the competition that it was banned under a questionable rule interpretation. Unfortunately, engineering brilliance in car racing can be overruled by the need to put on a good race for the fans (unfortunate) or by the need to hold down top speeds for safety reasons (probably a good idea).
Absolutely, there is far less room for error (likely no room in fact) for those 500 miles since at those speeds, lives are at stake. One teensy, little glitch in something as small as a misplaced fastener, and you could be primed for disaster.
Good point, Beth. It's amazing to learn that IndyCar's number one engineering challenge -- vehicle reliability -- is the same as for production cars. It's true they only need to go 500 miles at the Indy 500, but it doesn't mean that reliability is any less important. In fact, a simple failure -- like the one on Parnelli Jones' vehicle in 1967 -- can be devastating.
Nice job Chuck, on translating the thrill of racing into engineering challenges that other engineers, even if they don't work on the race car circuit, can relate to and are grappling with every day for their own types of products. Those minor design tweaks and keen attention to simulation outcome are what can set one company's offering apart from another--whether it's a highly competitive IndyCar race or components for commercial cars.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
