10 Things You Didn’t Know About NASCAR Pit Crews



Pit crews are instrumental parts of the NASCAR team. Functioning in the pit and behind the scenes, each member plays an important part in ensuring the car reaches the finish line. A well-oiled machine can consistently push a driver to the front of the race, but poor teamwork can break him when he's running neck and neck with his opponents. The following interesting facts are both fun and surprising for those who've never really paid close attention to the stuff that happens off the track.



Pit crew routines are not regulated by NASCAR

Although each crew essentially does the same routine, making a few minor changes of their own, they're not required by NASCAR to conduct the same sequence of actions. Because they don't have time to perform major work, strategy revolves around fueling and tire changes — the latter involves determining whether all four tires should be changed, or just the outside tires, which bear the most weight and pressure.

Crew members use liberal amounts of duct tape

The pros are always looking for a quick fix. During a race, a pit crew will use the strong, versatile tape to adjust body panels, hold parts together, fix hoses and hanging wires, and merely to mark where the jack post, left-front tire, and sign board will be located after the car hits the pit. It's such an important tool for the crew that it has earned its own nickname — "200 mph tape."

Crew members pound their cars with baseball bats and hammers

Another seemingly primitive way pit crews adjust their cars during races is to make use of baseball bats and hammers, pounding their uber-expensive machines when the situation calls for it. A misshapen body can affect how a car performs, causing it to fail to generate a sufficient amount of down force. With little time to spare, the strongest, quickest-swinging crew members take their best shots at the problem areas, impersonating their favorite baseball sluggers.

Crew members love piano bars

A heavily damaged car that's difficult to lift needs more than just the jack man. Instead, piano bars — long, sturdy bars; not the bar you visited during your last hotel stay — provide leverage for the crew to get the car off the ground so the members can do their work. Like duct tape and baseball bats, it's a simple tool with plenty of might.

Crew members exhibit higher heart rates on asphalt tracks than concrete tracks

Given the demands that come with being a member of a pit crew, it shouldn't come as a surprise that dealing with stress is a part of the job. But, as with any job, levels of stress can vary depending on the setting and the problems it presents. According to a study conducted by the University of North Carolina-Charlotte, members exhibit higher heart rates on asphalt tracks than concrete tracks. This may have to do with the heat of the tracks caused by the blacktop surface.

Crew members can earn close to six-figure salaries

Of course, pay varies by position and responsibility. For example, Jason Myers, the car chief for Carl Edwards until his termination in 2009, earned $140,000 in 2008 not including bonuses and other compensation. He was second-in-command to the crew chief, who boasted a salary of $500,000. Guys in lower positions but with lots of responsibility — such as those who work in the shop, travel to the races, and work on Sundays — can earn in the neighborhood of $75,000.

Crew members may frequently change teams

A pit crew change for the second consecutive season enabled Kevin Harvick to take the lead in this year's Chase. Out of the running, Clint Boyer, a Richard Childress Racing teammate, lent his crew to give Harvick a boost for the stretch run. An efficient crew can make all the difference in the world, which is why of the best crew members in the biz are highly recruited by opposing teams. Essentially, they can play the field, seeking the best possible offer.

It's a year-round job

Like modern athletes, pit crew members train year-round, sparing just a couple of weeks for rest in December. Beginning in January, they practice pit stops before the start of the season, and then take it up a notch during the season, practicing two times per week and working out rigorously. It's a constant battle to improve their efficiency so they can reduce pit stop times.

Many pit crew members are former athletes

In recent years, NASCAR pit crews have emphasized athleticism to meet the physical demands of pit stops. As every aspect of the sport has become more competitive, shorter pit times have become essential for crews, so meticulously crafted routines have become the norm. Tony Stewart, for example, employs Mike Casto, a former wide receiver from Glenville State College. Mark Martin employs Aaron Walker, who spent five seasons in the NFL. It's a great way for ex-athletes to stay in a competitive field and utilize their physical strengths.

Pit crews have their own all-star event

Held annually in Charlotte's Time Warner Cable Arena, the NASCAR Pit Crew Challenge is a competition featuring seven pit crew members from each team. When given a signal, each team lifts the car, changes the tires, unloads 18 gallons of water substituting as fuel into a fuel tank, and upon approval from NASCAR, pushes the car 40 yards to finish the sequence. If "fuel" is spilled, too much "fuel" is left in the dump can, a jack isn't raised high enough, or lug nuts are improperly tightened, then penalties are given. Through the years, the notable pit crews of Cale Yarborough, Bobby Allison, Richard Petty, and Dale Earnhardt have won multiple times.

Dora, A Domestic Robot, Visits The Big City, Tries To Find Cornflakes

Dora, a domestic robot devised and built by a group of European computer scientists led by the University of Birmingham, will make an appearance at the London Science Museum’s new exhibition of cutting-edge robots from the 1st – 4th December 2011.

The first video provides an overview of some of Dora’s basic capabilities.

Dora is a prototype domestic robot that is curious about its surroundings. It explores previously unseen environments to build up maps of its location that can be used when performing tasks for humans. It can work out which rooms are which by noting the presence of certain objects, for example, if it sees a kettle it knows it is in the kitchen, so if it has been asked to fetch a box of cornflakes it will also know that it is in the correct room to retrieve the object.

Dora, the robot, is trying to find cornflakes in a house. Instead of just exhaustively searching everywhere, Dora is equipped with probabilistic reasoning and planning to exploit the knowledge that cornflakes are usually found in kitchens. This is from the IJCAI ‘11 paper titled “Exploiting Probabilistic Knowledge under Uncertain Sensing for Efficient Robot Behaviour”.

Dr Nick Hawes, a developer of Dora from the University of Birmingham’s School of Computer Science, said, ‘Our research aims are to produce intelligent robots to assist humans in normal environments. To do this we need to enable them to use their senses, and all available information, to solve complex problems and interact with humans in natural ways, such as through dialogue.’

Dora will be on display with 20 other unique robots including swarming and swimming robots, exploring and humanoid robots. Roboticists from the UK and Europe will be on hand to demonstrate their work and talk to visitors.

Dr Hawes continued: ‘This exhibition is a great way to celebrate the 90th anniversary of the word ‘robot’ which was coined by Czech writer Karel Čapek. We are delighted that Dora has been chosen to take part and will be displayed amongst the best and most innovative prototypes from all over the world.’

8 Dangers Of Working From Home To Be Aware Of


Many people think working from home would be idyllic. No more getting up early to make a long commute, no more having to put up with crabby coworkers, no more wardrobe worries. You could make your own hours and have so much more free time. Working from home certainly has its advantages, but there are drawbacks as well. If you’re someone who has an opportunity to work from home for your career, here are 8 dangers of this situation that you should be aware of.
  1. Distractions – You may think working from home would have fewer distractions than a common workplace, but the opposite is often the case, especially when people find out you’re there during the day. The phone rings, people stop by, young children are at home or you notice a neglected household item that either needs to be either fixed or cleaned. The biggest distraction of all is when there is fantastic weather that lures you outdoors. All of these things can make it hard to concentrate on your job.
  2. Time management – All of these distractions can make it hard to manage your time effectively when you work from home. It’s easy to lose track of time when you don’t have a people around to remind you. Since computers and internet are what has made it possible for people to work from home, surfing the web and reading emails can also be big time suckers. It can be difficult to keep focused on the job and not get off track. On the other hand, you can also run the danger of being too focused and not taking a break when you need one.
  3. Self discipline – The key to making your home-based career a success is self discipline. If you’re not able to keep distractions to a limit and manage your time effectively, you’re in danger of not doing very well. Some people are not very self-motivated and need a boss or supervisor to provide the incentives for them to get their work done. Overachievers don’t know when it’s time to quit for the day. These people are not good candidates for working from home.
  4. Confusing priorities – Going to an outside workplace makes it easier to prioritize your duties. You do what needs to be done at work when you’re there and the same goes for when you’re home. Working from home can make setting your priorities a little more difficult. It can be hard to ignore an unfinished home project when you’re there all the time and pretty soon you find it easy to neglect your job. You also run the risk of immersing yourself in work because you never have to go home when you’re already there.
  5. Isolation – Another danger of working from home is the feeling of isolation. People who thrive on social interaction will find it difficult to be on their own for long periods of time. Pretty soon they find themselves missing even the most annoying of their former coworkers. Unless you’re fairly comfortable with spending lots of time with only yourself for company, don’t consider a home-based career.
  6. Out of the loop – Working from home can really make you feel out of the loop. You’re not getting the latest gossip around the water cooler or included in the discussions on local issues. The coworkers who used to include you in their social gatherings don’t think of calling you since you’re no longer around. This just adds to the feeling of isolation and could lead to depression.  
  7. Children – Many people decide to work from home while they have young children to care for. Although this can really save on day care services, it may have drawbacks. Nothing is more demanding than infants and small children. They don’t understand the concept of your career and can make it difficult for you to get any meaningful work done.
  8. Appearance – Working from home can really take its toll on your personal appearance. Since you no longer have to update your wardrobe or look good to impress anyone, you run the risk of really letting yourself go. A fully stocked refrigerator is in the kitchen and snacks aren’t just for coffee breaks any more. Since nobody is going to see you all day, why even bother getting out of your bathrobe?
Whether you are a remote worker or self-employed, working from home is a great option to have, but not without some perils. It’s important to look at the pro’s and con’s before making a commitment. Look carefully at your personal situation and character to see if you have the self-determination to make it work. Also be sure to give yourself some time to adjust to the freedom a home-based career provides.
