Theory of Machine In a four-bar chain it is required to give an oscillatory motion to the follower for a continuous rotation of the crank. For the lengths of 50 mm of crank and 70 mm of the follower, determine theoretical maximum length of coupler. The distance between fixed pivots of crank and followers is 95 mm Slightly less than 95 mm 45 mm Slightly more than 95 mm 95 mm Slightly less than 95 mm 45 mm Slightly more than 95 mm 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) (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 S₂/S₁ = r₁/r₂ (m.g + S₁)/(m.g + S₂) = r₁/r₂ ANSWER DOWNLOAD EXAMIANS APP
