What FRC Calculators do you want

[TheModMaster8]

Note: all abbreviation meanings can be found below.

I've developed an FRC calculator that can so far, take (Wheel Size)+(RPM)+(2 stage gearing)=(FPS). And a Linear Actuator Calculator that takes the (RPM)+(2 stag gearing)+(Thread Pitch)+(TPI)+(Actuator's overall travel distance)=(DPS) and (TTC).

So now on to my real question, what kind of calculator would you like to see implemented or have? (examples would be, Center to center gear/belt calculator,etc.) Thank you for time.


Abbreviations:
RPM = Revolutions Per Second
FPS = Feet Per Second
DPS= Distance Per Second
TPI = Threads Per Inch
TTC= Time To Complete
