In the aircraft and aerospace industry, the standards required for various components, parts, and specifications are considerably higher. Everything built for the aircraft and aerospace industry is light and strong. It is the “AND” part of that sentence that makes the parts expensive, not the “light” part. Automobile manufacturers today who build high-performance and sophisticated vehicles understand the “light” part, but not necessarily the “strong” part. But what they do understand is how much force can be applied to these parts before they succumb to failure.
Today’s brake rotors (or disk brake system) are built very light with advances in technology such as slotting, cross-drilling, cryo-treating and many other advances to allow the brakes to breathe better and last longer. However despite all this technology that goes into the rotors, they are still not strong enough to withstand a mechanic’s error. How often have you had a car pulsate when applying the brakes? The reason this happens is because the lug nuts on your wheels were not torqued down to specifications set out by the manufacturer. Every mechanic shop you walk into, you can always hear the distinctive sound of the air wrench being used to loosen and tighten parts and lug nuts. These air tools are capable of putting out an immense amount of torque, but that is where the problem starts. The torque setting on these air wrenches are preset to a single setting (usually the strongest), never changed, but used to tighten down everything on your car. BAD!
Today’s modern vehicles are built almost like airplanes and have very acute specifications that must be followed. The most commonly made mistake by mechanics and car owners are to over-tighten the lug nuts on the wheels of their cars. Some even go as far as jumping on the tire wrench to ensure that the lug nuts are “tight” and that the wheels will not “fall off” while driving. However, over tightening your lugs will lead to premature failure of your brake rotors as seen by warping or deformations in the rotor. It may also lead to wheel bolts “snapping” when over-tightening the wheels stretches and weakens the bolt.
It is therefore important to ensure that your lug nuts are tightened to the appropriate specifications and to do that, there are several things you can do. For most vehicles, the lug nuts need to be tightened down to 70-100 ft-lbs using a good quality torque wrench. However, you do not need a torque wrench to tighten your lug nuts correctly.
The approach I have always taken is to tighten the nuts as tightly as can be done with your fingers first. Then taking a tire wrench, tighten the nut without apply much effort until you feel some resistance. Then simply (without jumping on the tire wrench), put your body weight on the wrench until it stops turning. You do not need to jerk your body to ensure that there is more room to tighten. In general, if you follow this practice, you will put about 80-90 ft-lbs of torque onto the lug. Do this consistently for all your wheels to ensure that your brake rotors have maximum life. However, for best results, I still recommend acquiring a quality 1/2″ drive torque wrench, my favorite being the Neiko Pro line that I use religiously for every mechanical work conceivable.
It is a worthwhile investment and they typically range in price from $20-40, which is cheaper than a single brake rotor for your car. The brakes and wheels are the most important components of your car and therefore, requires the most care and attention. Go check your lug nuts today.
People who live in the state of Ohio may be in for a surprise when they open their mailbox. In this state the Bureau of Motor Vehicles sends out 280,000 requests a year to see proof of insurance. Once someone receives one of these notices in the mail they only have three weeks to prove they have insurance. Although it’s obviously mandatory to have car insurance, some people forego it because of the price. There are ways to find affordable car insurance and some are not things most people are aware of including:
o Using one insurance company for all your policies including car, home, health and life. Insurance companies give discounts to individuals who purchase more than one type of insurance from them. Ask your health insurance or life insurance agent about a quote for car insurance.
o Buying a car that costs less to insure. Most people never consider the insurance costs that are associated with a particular type of car before they buy it. Call several insurance agents and ask for quotes on a car you are considering buying. You may be surprised to learn exactly how expensive it is, and if you find this out before you finalize the sale, you can save yourself a lot of money.
o Mention that you have a car alarm or consider getting one. A car alarm is a great idea for many reasons including the reduction you are likely to experience in insurance costs. Any effort that you make to keep your car safer is viewed in a good light by the insurance company. You’ll have to be prepared to show proof that the car alarm system is indeed installed.
The most important factor in determining your car insurance rates is likely your driving record. If you have been in more than one accident in the last few years or you have a pile of speeding tickets with your name on them, you are obviously going to have a more difficult time getting an affordable rate. If this is the case, make a resolution to start driving safely now and you’ll see your rates steadily drop.
The Spanish language is becoming increasingly more important to speak and understand. More than 420 million people speak Spanish, including those who speak it as a second or third language. Approximately 17 million of those are in the United States, making speaking Spanish more than just a passing fad. Fortunately, there are many online resources geared towards helping people learn how to speak Spanish.
Learn Conversational Spanish
The website, studyspanish.com, provides people with the opportunity to learn conversational Spanish. Although this program will not help you achieve fluency, by reading the lessons and repeating sounds and phrases with the audio attachments, you can be well on your way to carrying on a conversation. Sample beginning lessons are available online, and students can add to their knowledge with the purchase of CDs.
Courses, Tutors and Games in Spanish
Websites like 123teachme.com provide grammar, vocabulary, verb conjugations and sounds, like the other websites, but they also incorporated games and quizzes. These games and quizzes use vocabulary and phrases to test students knowledge and memory. People using this site can also work with Spanish tutors, people who know the language fluently, to get one-on-one help and accelerate the learning process.
Use Videos on Google and YouTube
Videos are available on YouTube and Google, and allow Spanish students to hear how the words are said, including accents and emphasis, but also see how they're said. Some of these videos use visual aids, displaying words and their pronunciation, like a book and audio tape would do, while others use people. The videos are for the beginning and advanced learners, depending upon the individuals needs and desires.
Learn Practical Spanish
Websites like e-spanol.hu/en outline the basics of Spanish, including grammar, vocabulary and expressions. This website provides games, quizzes, tests, word practices, audio videos and transcripts for students to test their knowledge and maximize they're Spanish skills.
