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 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 ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The Grubler's criterion for determining the degrees of freedom (n) of a mechanism having plane motion is (where l = Number of links, and j = Number of binary joints) n = 4(l - 1) - 3j n = 3(l - 1) - 2j n = (l -1) - j n = 2(l - 1) - 2j n = 4(l - 1) - 3j n = 3(l - 1) - 2j n = (l -1) - j n = 2(l - 1) - 2j ANSWER DOWNLOAD EXAMIANS APP
