Yes, your are certainly right, these documents are a good representation of the system making this tank work. I have a few more sources were I can try to find the answer I was looking for, but I think I have enought information. Thanks a lot for you research, you all helped me a lot with this.

Yes, you link is good, it helped me to understand the formula I used, but I don't understand why I should use radian rather than Rpm (I mean, all my values are rpm, why bother convert them if my formulas used rpm). I'm not a physicist, so I don't really know, is the result more accurate using...

Nice!

Hi, No, I don't know the meaning of jump, I was probably going to be my next question. There is no other information on this jump column on the sheet paper (I'll share all the data I have as attached file), so if anyone knows about it, feel free to help us. Hi, SophieCentaur, I attempted...

That is certainly the explanation. Thanks a lot for your help!

I'm not totally sure to understand :-(, sorry. Here's the gear ratios of the vehicule (attached file, first column) Final Drive : 8.4:1 or 1:8.4, I have two contradictory source. How do I get to 1:13.4? If it is just a multiplication of data I already know, I won't use it in calculus, but can...

Hi, thanks a lot, I'm sure I will love Physics Forum :cool: if I understand well, this gear is there to reduce the speed of the engine and increase the torque (because it is needed), exactly as the final drive and gear box ratios do. Do you know how I could include it in the calcul from speed...

As I was looking in the caracteristics of an old tank, I found a number that I could not get anything of on the web. It is called "entire reduction ratio" and was presented just under the gearbox caracteristics. His value is 1:13.4. My question is : is it useful? Does this value have relation...

Hi, I'm a student with license in history and math (But unfortunately, almost no physics) and I'm looking for help to work with historical machine (steam machine, old cars, Worl war 2 tanks...) and all the physics calculus that come with it. Hope I will enjoy my time on PF :-).
