What is the acceleration in each gear of the 1993 Jeep Wrangler YJ?
Really stuck with this… Does anyone know?
Or is there some way of finding it out through the use of formulas?
Let’s say its a 4-cyclinder with a 2992 RPM, with a wheel diameter of 30″ and the gear ratios are 3.93, 2.33, 1.45, 1.00. 0.85 – from first to fifth respectively.
Does that information help at all???
Or do I need some more information to find the acceleration in each gear?

there are a couple of websites with formulas for this idk if you wanna try your luck at math or not but here is two:

you need to know the velocity, speed and a ton of other things… it can get complicated. i hope the web sites help.

Hi,
Do you mean What is the acceleration in each gear? or do you mean what is the top speed?
If you mean what is the acceleration then this can’t be calculated simply. It would require multiple equations taking into account, mass, air resistance, friction, horsepower, torque etc…
How ever I can tell you that as you go into higher gears the rate of acceleration decreases. So say in 1st gear you accelerate at 20m/s/s and then in 2nd gear you will accelerate at 17m/s/s then 3rd 14m/s/s and so on.
And because the amount of horse power is constantly changing in an internal combustion engine it is near on impossible anyway to calculate the acceleration. It would be possible to calculate it at one exact RPM i.e 5,300 RPM but at 5,301RPM it would be different again due to the amount of friction changing and the power being produced changing.
If you meant what is the top speed in each gear then this can easily be calculated. Just search “top speed calculator” in Google and there will be heaps there. Just choose the easiest one to use.
Hope this helps.
