Warping Automobile Disk Brake Rotors Are Preventable

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.

Image Optimization for SEO – Best Practices

Quality content is the key to SEO success. Content doesn’t just mean your text contents. Images must be an integral part of your content strategy. At times, single images can be far more effective than your 1000 word blog post. It also helps you improve blog post quality and performance.

Images, Infographics, Videos and all other multimedia contents on your web page will help you in increasing the user engagement on your site and makes the visitors stay on your site for longer duration which helps in reducing the bounce rate.

Not just adding images to your contents, you should also optimize those images for better SEO performance. Optimization of images must be the one important aspect of your on-page SEO process.

If you are using images in your content, there are many aspects to be considered related to SEO.

Relevancy

Using images doesn’t mean that you should fill up your content with loads of pictures. You should use it only when it is required and also you should use images that are more relevant to your content.

Placement of your images is an another important aspect. It should be placed at a relevant location in your content according to your text content.

Use original images

Originality always helps in improving your user experience and your authority. Usage of original images will be helpful in improving your SEO performance. You can create original images with a graphic designer or you can take your own photographs with a quality camera. It is the reason top White hat SEO companies employ talented graphic designers for creating quality images.

If you are not able to employ an in-house graphic designer or if you are running out of time, you can always use high quality images from the web. But the important factor to be considered is it should be copyright free.

There are many tools available for getting copyright free images without any cost. The most popular ones are Unsplash, Flicker, Freeimages.

Image Size

Images are the main source for damping your site’s speed. And site speed is a crucial factor in your SEO performance. So, you should be extra cautious in using images without compromising your page speed.

It should not also affect your image quality, you should have a correct balance between. You can achieve this by reducing the file size by compression. You can use tools like Photoshop for compression.

File name

Search engine crawlers are visually impaired, it can even interrupt a 5000 word text content, but it cannot interrupt a single image and what the image is about. It is the reason using a keyword rich file names for your images is an important aspect in image optimization.

Google bots and other search engine crawlers can read your image’s file name and if it is named with your target keyword, it gives a signal to search engines about the image topic and thus helps your SEO performance.

For example, if your image is related to selling sports shoes, rather than using the file name as “IMG_89868″ you can use it as “Black_Tennis_Shoes”.

Alt text

Similar to the file name, search engines can read Alt text of the images. Alt text is known as “Aleternative Text”, is an HTML attribute used to describe the content of images.

You should use Alt text which is relevant to your images and it should be clear and descriptive. You can use your target keywords in the Alt text but be cautious about Keyword stuffing.

If you are not focusing on Image optimization, you are missing a huge opportunity in improving your SEO performance. You can use above mentioned best practices in your on-page optimization process.

Teenage Weight Loss – How Teenagers Can Safely Lose Weight

Teenagers with body mass measures between 25 and 30 require immediate medical attention. The internal stress caused from so much weight almost guarantees the premature development of medical problems such as diabetes, heart disease, cancers, and stroke.

There's no question that aggressive weight loss methods are necessary and these teenagers need to be followed by medical experts for years to come. But what about teenagers with body mass measures just below 25? Is it safe for this group of overweight and mildly obese teenagers to lose weight?

The verdict is still out – the weight loss community continues to wait for more evidence supporting aggressive weight loss methods for overweight teens. I say while we wait, let's lose some weight.

But we do not need to be so aggressive with this group. Overweight teens need to lose weight, but in a slow, gradual process. Lasting weight loss and the development of positive habits should replace the push for immediate weight loss in adolescents with body mass measures between 22 and 25.

The there's the teenager wanting to lose weight for purely cosmetic reasons. How do we approach this fragile situation as parents and professionals? We can not just say no to her for fear she might turn to unhealthy means to lose weight. But we can not just give him a green light and say go for it, either.

The rest of this article focuses on the cosmetic teenage weight loss dilemma. The best thing I can do is at least provide some ground rules for teenagers with body mass indices less than 22 who insist on losing weight.

Cosmetic Teenage Weight Loss – The Ground Rules

Here's a simple, straight forward list of ground rules for teenagers wanting to lose weight for cosmetic reasons:

  1. Losing weight with a body mass index less than 19 is not recommended and might even be harmful. Things like eating disorders, endocrine abnormalities, stunted growth, and anorexia are all well documented consequences from unnecessary teenage weight loss.
  2. Teenagers with body mass measures between 20 and 22, can lose 5 to 10 pounds in a safe and effective manner.
  3. The primary mechanism for teenage weight loss is always the "burning" of excess calories through increased physical activity. A combination of aerobic exercises and resistance training works fast and produces the best results.
  4. Teenage weight loss by restricting calories should be kept to a minimum. A slow, gradual, and controlled restriction of calories is key. I recommend starting with a 5% reduction of calories from baseline for two weeks. This is followed by a 10% reduction for one week and then a 15% reduction (if necessary) for one week.
  5. Dedication to a consistent exercise program typically produces the weight loss desired without any changes to the caloric intake. A more natural way to reduce calories comes from eating a more balanced and nutritious diet, including more servings of fruits and vegetables.
  6. Emphasizing consistent exercise and a nutritious diet is often all that is needed for a teenager to drop some weight, firm and tone muscle, and achieve her "cosmetic" goals.
