This calculator is designed to allow you to determine the spin rate needed for a specific G force at that radius away from the center.

Remember that to avoid the "coriolis effect" you should have the spin something less than 4 RPM.

The default G force is One G (9.81 m/s or 32.2 ft/sec)

cir = 2 * pi * r   v = square root (a*r)   t = cir/v   rpm = 60/t

a = acceleration (meters/sec/sec)
v = velocity (meters/sec)
r = radius (meters)
t = time (seconds)
