Hi Chris, Thanks! Note that it's a bit more complicated than where the center of mass is: you need the moment of inertia. For example, imagine comparing (a) a point mass at r=1ft and (b) the same mass divided into two bits at r=2ft and r=0ft. The center of mass in case (b) still rotates with r=1ft but the cases aren't equivalent: you need 2x the force in case (b). [1]
But you may well be right that the effective radius is under 1ft! Jeff [1] Doing the math: F_a = m (ω2πr)^2 / r = m * r * (ω2π)^2 F_b = m/2 (ω2π(2r))^2 / (2r) + 0 = m * r * 2 * (ω2π)^2 F_a = 1/2 * F_b On Wed, Mar 27, 2024 at 1:18 PM Chris Lahey <[email protected]> wrote: > I addressed this in my other email, but this is a good example.
