Anything less than 1 inch is referred to in fractions. As you can see, understanding fractions is fundamental in comprehending the English system. On the other hand, the metric system is designed so that fractions are almost unheard of. Instead of using fractions, one simply drops down to the next level.
If you have a bolt with a head that is less than 1cm, which is a common occurrence, instead of using a fraction to designate the size, you merely go to the next level, which is measured in millimeters.
It really is not that difficult to comprehend, especially once you get some hands-on experience. Just remember that a different set of tools is needed to work on each type of car. A good mechanic needs to have both. Numbers also come into play in many other ways, such as calculating torque, engine size and displacement, horsepower and firing sequence. Torque is expressed in foot-pounds, and is a measurement of the force needed to tighten a bolt.
I had no clue where to put this so if this is the wrong place feel free to correct me. I was wondering how good you have to be at math to hack it as a mechanic. I'm really good with languages and stuff but when it comes to math I have some extreme difficulties and I was wondering if that would play a part in being a mechanic. If I were to work hard enough do you think it's possible? Yea, figured. Guess I gotta not skip math anymore.

Lesson 2 g-wonlinetextbooks. Case Study 16 g-wonlinetextbooks. Get in Touch. Units begin with Career Profiles based on interviews with practicing automotive technicians who explain how and why math is important to their work. The Career Profiles provide context and motivation for students and answer the question "why study math? Word problems also reference Concern-Cause-Correction language, which integrates a diagnostic problem-solving model with mathematical problem-solving.
Math for Automotive Technicians is well suited for use as either the core text in a dedicated applied math course or as a supplemental text in an automotive technology program.

Some four-wheel-drive models have gear-reduction axles, which allows major torque multiplication at crawl speeds, as well. These ratios are what determine what the speedometer says at any given speed.
If even one of the gearing components is changed to a different size, the speedometer will read too fast or too slow. Math is used to determine the size of each cylinder, and each of those is added up to a total, which is the displacement of the engine itself. Combustion chamber sizes must be known and calculated, as well as oil pan capacity and the cooling system capacity. Each of these components is dialed in using math in conjunction with special tools.
