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 S₁/S₂ = r₁/r₂ (m.g - S₁)/(m.g - S₂) = r₂/r₁ S₂/S₁ = r₁/r₂ (m.g + S₁)/(m.g + S₂) = r₁/r₂ S₁/S₂ = r₁/r₂ (m.g - S₁)/(m.g - S₂) = r₂/r₁ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine The two links OA and OB are connected by a pin joint at O. If the link OA turns with angular velocity ω₁ rad/s in the clockwise direction and the link OB turns with angular velocity ω₂ rad/s in the anticlockwise direction, then the rubbing velocity at the pin joint O is (where r = Radius of the pin at O) ω₁.ω₂.r (ω₁ - ω₂) 2r (ω₁ - ω₂) r (ω₁ + ω₂) r ω₁.ω₂.r (ω₁ - ω₂) 2r (ω₁ - ω₂) r (ω₁ + ω₂) r ANSWER DOWNLOAD EXAMIANS APP
