All in one FRC Calculator by 5492

[TheModMaster8]

On behalf of Team 5492, I've developed a calculator that calculates FPS. It takes the following inputs: wheel size, motor RPM, (gear, belt or chain) tooth numbers and outputs the FPS. This program is still in the beta testing stage and I am looking for feedback as well as features you may want to see added!
this program is compatible with both Mac and Windows, it requires java to run.

if you run into any crashes, bugs or errors, please post a comment explaining what happened and or any error logs that my appear

If you wish to only do a single stage gear reduction put
'1' in both the "Ratio 2 Gear #3" and "Ratio 2 Gear #4"

I must give full credit to my brother (for the formula, not programming). He developed the formula all on is own. While he may not have been the first to discover it, he did come up with it all by himself
