THE ART OF SIDEWAYS! LESSON#3

CARvs.SPEEDBUMP

t0k

NEVER THOUGHT i WOULD BE IN THIS SITUATION….THAT MOMENT WHEN U SEE A STEEP INCLINE, BUMP, DECLINE, etc 😦

MY E36 WAS SLIGHTLY LOW, MY S6 WAS LOW, BUT NOW MY Z33’S NEW BUMPER HAS BROUGHT ME IN A TERRITORY THAT I THOUGHT I AVOIDED. YES I’M TALKING ABOUT HAVING A 2″ – 5″ GROUND  CLEARANCE. SOMETIMES i JUST DON’T WANT TO DRIVE MY CAR ANYMORE, I ALWAYS HAVE A FEELING THAT I WON’T BE ABLE TO MAKE IT THROUGH A ROAD TRIP. ALWAYS THINKING IF I’LL NEED TO PARK FAR AWAY, JUST TO GET TO THE DESTINATION I DROVE TO. THEN I REALIZED…..THE NINJA ART OF SIDEWAYS HAD TO BE MASTERED.
wARNING: 1. (MANUAL TRANS DRIVERS) DO NOT ATTEMPT THIS AFTER DOING A LEG OR LOWER BODY WORKOUT, YOU WILL FAIL……OR GET A CRAMP WHILE DOING IT.  2.) IF YOU DRIVE AN AUTOMATIC…GET A MANUAL (LOLJK) 3.) THE APPROACH OF THE TECHNIQUE IS UNIVERSAL, BUT DEPENDS CRITICALLY ON THE SITUATION (SPEED BUMP, DRIVEWAY INCLINE/DECLINE), ETC.

STEPS:

1. KNOW YOUR SITUATION AND HISTORY: 1)WHAT CLEARANCE DO MY FRONT, REAR, SIDE SPOILERS HAVE, 2) CAN I ACCOMPLISH THE CHALLENGE WITH THIS ART, 3) WHY IS MY CAR SO LOWWWWW 😦 # IF YOU CAN’T PASS #1 THEN GO PARK AND WALK#
2. IF APPROACHING THE INCLINE FROM THE LEFT SIDE OF VEHICLE, APPROACH THE INCLINE AT AN ANGLE SO THAT THE LEFT TIRE CLIMBS THE INCLINE FIRST.
3. FOLLOWING THIS, BEGIN TO TURN YOUR STEERING WHEEL SLOWLY SO THAT YOU CAN GUIDE THE RIGHT TIRE ON TO THE BUMP. (THIS IS THE MOST CRUCIAL STAGE SO TAKE YOUR TIME) FOR SPEED BUMPS YOU HAVE TO MAKE SURE THE RIGHT TIRE (OR LEFT IF YOU STARTED WITH THE RIGHT TIRE) ADVANCES ON THE BUMP BEFORE THE LEFT TIRE CLEARS THE WHOLE SPEED BUMP
4. FOR THOSE NOT GOING THROUGH A SPEED BUMP, YOU SHOULD BE SAFE. HOWEVER BE CAREFUL, IF THE HILL IS TO STEEP AND YOU HAVE A STIFF SUSPENSION SET UP ONE SIDE OF THE REAR WHEELS MIGHT BE SLIGHTLY OFF THE GROUND. THIS MAY CAUSE YOU TO GET STUCK ESPECIALLY IF YOU HAVE A REAR WHEEL DRIVE RIDE. (NOT AS DRAMATIC AS PHOTO)

5. CONTINUING ON WITH THE PERSON STUCK AT THE SPEED BUMP, AS YOU APPROACH THE HALFWAY MARK WE GO BACK TO STEP ONE OF THIS MANUAL. (PAY ATTENTION TO EXHAUST CLEARENCE, SWAYBARS, AND SIDESKIRTS) USUALLY THE REAR ISN’T AS LOW AS THE FRONT, BUT WITH THE CURRENT STANCE MOVEMENT CARS I MAY BE WRONG.

6. IF YOU HAVE LOW SIDESKIRTS OR YOUR REAR IS LOW AS WELL, TRY TO CLEAR THE SPEED BUMP IN AN ANGLE AFTER YOUR FRONT RIGHT TIRE (IN THIS SITUATION) CLEARS THE SPEED BUMP. SO YOU WOULD TRY TO GET THE LEFT REAR TIRE TO CLIMB THE BUMP BEFORE THE RIGHT. IF YOU DON’T HAVE LOW SKIRTS OR A SIGNIFICANTLY LOWER REAR YOU SHOULD BE FINE EXITING. (WARNING: YOU WILL GET STUCK ON THE SPEED BUMP IF YOU ARE TOO LOW TO CLEAR IT WITHOUT DOING AN ANGLE APPROACH FROM THE REAR AS WELL.

TIPS: DO NOT APPROACH THE BUMP TOO FAST UNLESS YOU ARE POSITIVE YOU CAN MAKE IT. 2.) ITS EMBARRASSING TO GET STUCK, BUT MORE SHAMEFUL TO DAMAGE YOUR CAR JUST BECAUSE YOU WANT TO GET OUT OF THE SITUATION (ITS YOUR CAR, NOT THE PEOPLE RECORDING). 3) ALWAYS THINK AND KNOW YOUR SITUATION AND SURROUNDINGS, THIS IS THE MOST CRITICAL. IF ITS A HIGH TRAFFIC AREA DON’T TRY TO CLEAR IT IF YOU AREN’T 95% SURE. 4) IF YOU GOT YOUR CAR INTO A CAR SHOW, YOU CAN GET IT OUT TELL PEOPLE TO MOVE CAUSE YOU HAVE TO DO THE TECHNIQUE!! 5) CARRY A SET OF TOOLS TO EASILY REMOVE PARTS (BUMPERS USUALLY) ITS CHEAP TO CARRY A RATCHET WRENCH OR SOMETHING WITH YOU FOR THAT ONE MOMENT. 6) FINAL TIP……YOU DID THAT TO YOUR CAR, IT SHOULD NOW BE A LIFESTYLE CHOICE….OR JUST GET AIR SUSPENSION.

HERE IS A VIDEO SHOWING SOME GOOD TECH

 

Those LEDS make me bend my knees Lesson#2

Lesson #2 LEDS (light-emitting diodes)

We see them everywhere now, ever since Audi revolutionized the automotive world with the A5 and its brilliant LED’s no other major car company–except BMW’s Halo lights–was in their league in terms of looks! Well we are going to go back to chemistry class and learn about how these brilliant and innovative lights work!

I really don’t want to confuse anyone to begin with so I’ll try my best to skip the more detailed parts….hopefully! So in essence a LED is formed between two intrinsic or extrinsic (contains impurities) semiconductors, a n-type and p-type. When these two semiconductors are put together they form a junction called a P-N junction (predictable name).  The P side is dominated by positive charged “holes” where as the n type has a high negative charge density. The junction created by the two semiconductors serves as the determinate for current flow. Look at the figures below (provided by imagesco.com)!

Now we are getting to the important part of this subject! The electrons want to fill the holes on the P side of the junction, but in order to do that they have to overcome the energy barrier in the junction in order to make it on the other side. The electrons are currently in a lower energy level, but as they make their transition through the junction they release energy equal to that band-gap in the form of photons in order to move across (they move when a voltage is applied to overcome the energy barrier). This energy goes into emitted infrared or visible light in LED’s. The most common semiconductors used are Silicon (Si) or Gallium (Ga), in order to get different colors the chemical composition is changed with the addition of various compounds most including phosphorus. So LED’s are graded on their specific wavelengths and intensities based on the materials used to make them. Since LED’s don’t have any moving parts it reduces their chance of being damaged due to vibration or shock and are also heat resistant 200K/watt. 

So in short that is how those LED’s most of us have on our cars work, I know a lot of scientists and engineers might have something to say about the choice of words I used to describe the processes, but hey I got my Chemistry degree I can say whatever I want right! The application list for these parts is extensiv
“rice” their rides by going on an LED frenzy! There are some applications where the traditional halogen light bulbs still look better then their newly popular LED sisters.

Lesson #1 Fiber or Fibre

Alright so this new technology is everywhere and people love it for its durability, lightweight, and beauty. The first thing you should get right is the spelling, so going to the alphabet spell it out C-A-R-B-O-N F-I-B-E-R, correct?? Yes and no, all English speaking country’s use FIBRE where in the U.S. they use FIBER I guess there is still tension between England and the U.S. on how to speak proper. So if you’re out of the states remember to switch you E and R if the situation arises.

Next: What is this Technology??

* We hear things like lightweight, ultra weave (uhh not hair), super durable, excellent quality, dry, and wet carbon yet there isn’t a concrete description on most products on what CF is.

  1. It’s a stiff yet brittle fiber-reinforced polymer, has low density and high strength. Its high thermal conductivity and low coefficient of thermal expansion give it its high resistance to thermal shock. So basically its very strong and its chemical structure helps in resisting high temperatures (>600 degrees_)
  2. All grades of Fibre are made by thermal degradation of a polymeric organic precursor. A polymer is simply a long chain of repeating units; for plastics the main component will be carbon. So a simple polymer would look like this -(-C-C-C-C-C-C-C-C-)-.
  3. Most are created from three carbon-containing precursors: pitch, rayon and polyacrylonitrile (PAN)
  4. Space Shuttles, F1 cars, and some CF manufacturers use SiC (silicon carbide if I still remember my chemistry lol) coating on fibres to further enhance resistance to heat and oxidation.
  5. The difference in DRY vs. WET fibre is determined by the heat treatment on the fibres; in short more time spent with the heat treatments will give the fibre better mechanical properties and durability (DRY) instead of one that might contain more impurities (WET).
  6. Pitch and PAN fibres are much stronger than rayon created fibres
    1. Pitch – residue left after distillation of crude petroleum and coal. It has high carbon content and very cheap, mostly composed of aromatic and cyclic aliphatic hydrocarbons that are high in mass. So basically its composed of molecules of carbon formed as a six-membered ring or hexagon.Pitch is heat treated at around 750K creating a type of mesophase (liqiuid crystal), this is then melt-spun into fibers. After thermosetting they are carbonized by heating the compound at temperatures of >1300K. Carbonization provides the removal of impurities such as Hydrogen and Oxygen. This process creates the graphene like sheets that are heat treated to create the graphite-like structure we are familiar in seeing; this process also removes Sulfur and Nitrogen impurities. A protective coating is usually required after in order to resist reactions with other elements in high temperature settings.
    2. PAN fibres usually contain lower Nitrogen content than pitch depending on the grade. Not to get so long winded in the process, but its prepared by starting with the polymer and taking it to these four steps: 1) cyclization, 2) dehydrogenation, 3) oxidation, 4) carbonization.

Passing Grade A-

The Winner in the spelling of CF goes to FIBRE, since we are dealing with lightweight material and the U.S. has a overweight problem with its citizens its only logical to accept the FIBRE spelling of the Queen. Sorry U.S.
