Sphere in Cylindrical Track Angular Natural Frequency Equations and Calculator

ωn = [ ( 5 g ) / ( 7 ( Rt - Rs ) ] (1/2)

Where:

g = Acceleration of Gravity, ( 32.2 ft/sec2 ),
Rt = Radius of Track (ft),
Rs = Radius of Sphere (ft),
ωn = Angular Natural Frequency ( rad/sec or Hz)

1 rad/sec = 1/( 2π ) Hz
