My thanks to whoever posted the note on K-Factor from Eham.net!
All you need to know for the rotator is how much torque it will handle,
Calculate the K factor for the antenna, The rotator torque needs to be
greater than the calculated K factor for the antenna(s).
Not really
K factor comes out in a force * distance (foot pounds) but it's not a
torque because acceleration doesn't factor into it.
Inertia would be mass * distance ^2
Acceleration would be a angle/time^2
T = alpha * I = mass * distance^2/time^2
Torque is force * distance = (mass * distance/time^2) * distance
You could assume some nominal acceleration (1/sec^2) I suppose and then
hope that the scale factors come out right. Maybe for feet and pounds
it does?
