Theory of Machine In a mechanism, usually one link is fixed. If the fixed link is changed in a kinematic chain, then relative motion of other links Will not occur Will remain same Could change or remain unaltered depending on which link is fixed Will change Will not occur Will remain same Could change or remain unaltered depending on which link is fixed Will change 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 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 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 = [(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 ANSWER DOWNLOAD EXAMIANS APP
