Math - Ratios

[TheDh0ffryn]

very informative, but im having issues with mechanical ratios, what im doing is supercharging a car but due to space constraints im going to have to use a reduction style setup and im trying to work out how big my pulleys should be, the only 3 solid inputs i have is 1:the engine pulley 127mm, 2: the engines rpm 5800, and 3: what i need the final pulley to spin at 10'500rpm, i have tried different calculations but all produce different answers, can you help at all?

[TheDh0ffryn]

as a note it will be like this, Engine pulley (EP), Extension shaft pulley(ESP), supercharger pulley (SP)

EP>ESP======ESP>SP

noting that EP is set at 127mm and 5800rpm and SP needs to be at 10500rpm (with a minimum pulley size of 75mm)

[TheDh0ffryn]

@TheDh0ffryn also forgot i would like to try to make the Extension shaft rotate pretty slow without the pulleys being too big

thumbs up if you have maths gcse today 

[katieoxtoby]

I agree...if I'd had a maths teacher like him then maybe I wouldn't be having to watch videos like this at the age of 28...I'd have been motivated to pay attention to his straight-forward explanations by his handsomeness...

[tongtong168]

I wish i have him as my tutor or teacher. He is cute.

[VickyJ31520]

Wow! I think I know how to solve ratio's now, however I am going to watch a few more videos and browse for some practice problem's to make sure.
