Ever wonder what those volumes given for vehicle engine sizes actually refer to? This video explains vehicle engine sizes using math and a partly dismantled engine. Math concept involved: Applied problem involving volume of a cylinder
@@rocky-jp5rp its literally a 6th grade school subject of finding the volume of a cylinder. again, it has practical application and if you asked students to do this, they would actually be interested in how to use formulas and measuring.
For all these years I did not understand and nobody could explain it to me, and now you have done so in such a simple way, now I see the light, Thank you!!!!
When I was in the tenth grade in high school (this was the 2000-2001), I had to take geometry. As expected, we had to learn pi R squared and a lot of other stuff. I did okay in the class, but like most other kids, I thought it was pointless. This is the first time in my life that I've learned that all that geometry stuff has a real-world application. Betcha a lot more kids would be more motivated to be good at math if they learned how these formulas are used in the real world!
Thanks so much for this! I feel very strongly that when we see how concepts can be used in real-life situations is when we can truly appreciate and learn them authentically. The real-world 'why do we need to know this' is the necessary motivation to learn the math! 🙂
@@AllAroundMathGuy I agree! The method of teaching math is all wrong. Teachers make you memorize formulas, in the same way you memorize dates in history class. This doesn't make any sense, because if you use math in work environment, you can always look up formulas. I know I would have paid more attention in math class in school, if we were taught useful real-life examples.
you are so correct it's just like when I was taught data structure and algorithms in school here in Nigeria. the way it's been taught is sickening we only read to make good grades but now am trying to program I see the benefit of those
@@gozie.chatdesk2173 Sounds like all schools are the same, no matter which country someone lives in. Same in the US, there's an emphasis on memorizing formulas. Kids have to memorize the formulas just to pass the test, then they promptly forget them after taking the test. In the real world, you can look up formulas in a book, or on the internet. I think the emphasis should be on understanding how math works and real-life applications. Not on memorizing formulas to get good grades on a test.
You gave a real world scenario where this math would apply and a lot of teens in school can relate because they like cars and this actually did a better visual job of explaining how to find the volume of a cylinder better than my algebra and geometry teacher ever could
Thank you so much! Learning is indeed much easier when connected to a real-world situation, both as motivation to learn a concept and something that our brain can make sense of rather than just an abstract concept. 🙂
Extremely helpful, I appreciate you taking the time to partially disassemble the engine and actually physically measure the cylinders for the demonstration.
This ones surely the best explanation that I had come across on you tube on CC! Talk about amalgamation of practical and theory then here we go!! Brilliant job!!!
thank you for the explanation of engine sizes and how to work it out ourselves, really helpful to understanding what 'CC' refers to when looking at car specs.
I was looking to find a good explanation of engine displacement for an intro stats class where a data set on car info used this measurement. All the explanations/definitions were very technical. I think actually seeing the inside of the engine block was very helpful, and the measuring and then confirming of the size of the engine. Cool! I am showing this to my students.
Brilliant! I always had a feeling that's what the liter number referred to but I couldn't quite articulate it. Thank you sir for doing what I could not!
Thank you for explaining it. Now I understand what that means. I wasn't quite sure why it was so important to know when ordering car parts. The year, Make & Model is not enough. When a mechanic talks about an engine, 99% of the time they mention the engine displacement for identification purposes I assume. I really thought I would have to watch a slew of videos on this to find the best explanation but this was the first and only video I had to watch on it so thank you so much.
