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) = r₁/r₂ S₁/S₂ = r₁/r₂ S₂/S₁ = r₁/r₂ (m.g - S₁)/(m.g - S₂) = r₂/r₁ (m.g + S₁)/(m.g + S₂) = r₁/r₂ S₁/S₂ = r₁/r₂ S₂/S₁ = r₁/r₂ (m.g - S₁)/(m.g - S₂) = r₂/r₁ ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine In a band and block brake, the ratio of tensions on tight side and slack side of the band is (where μ = Coefficient of friction between the blocks and the drum, θ = Semi-angle of each block subtending at the center of drum, and n = Number of blocks) T₁/T₂ = [(1 + μ tanθ)/(1 - μ tanθ)]n T₁/T₂ = (μ θ)n T₁/T₂ = μ. θ. n T₁/T₂ = [(1 - μ tanθ)/(1 + μ tanθ)]n T₁/T₂ = [(1 + μ tanθ)/(1 - μ tanθ)]n T₁/T₂ = (μ θ)n T₁/T₂ = μ. θ. n T₁/T₂ = [(1 - μ tanθ)/(1 + μ tanθ)]n ANSWER DOWNLOAD EXAMIANS APP
