Theory of Machine For an isochronous Hartnell governor (where r₁ and r₂ = Maximum and minimum radius of rotation of balls respectively, S₁ and S₂ = Maximum and minimum force exerted on the sleeve respectively, and M = Mass on the sleeve) S₁/S₂ = r₁/r₂ (m.g + S₁)/(m.g + S₂) = r₁/r₂ (m.g - S₁)/(m.g - S₂) = r₂/r₁ S₂/S₁ = r₁/r₂ S₁/S₂ = r₁/r₂ (m.g + S₁)/(m.g + S₂) = r₁/r₂ (m.g - S₁)/(m.g - S₂) = r₂/r₁ S₂/S₁ = r₁/r₂ ANSWER DOWNLOAD EXAMIANS APP
