Theory of Machine The ratio of height of Porter governor (when length of arms and links are equal) to the height of Watt's governor is (where m = Mass of the ball, and M = Mass on the sleeve) (m + M)/M M/(m + M) (m + M)/m m/(m + M) (m + M)/M M/(m + M) (m + M)/m m/(m + M) ANSWER DOWNLOAD EXAMIANS APP
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) S₂/S₁ = r₁/r₂ (m.g + S₁)/(m.g + S₂) = r₁/r₂ (m.g - S₁)/(m.g - S₂) = r₂/r₁ S₁/S₂ = r₁/r₂ S₂/S₁ = r₁/r₂ (m.g + S₁)/(m.g + S₂) = r₁/r₂ (m.g - S₁)/(m.g - S₂) = r₂/r₁ S₁/S₂ = r₁/r₂ ANSWER DOWNLOAD EXAMIANS APP
