Machine Design In a band and block brake, the ratio of tensions on the tight and slack sides of band is given by (where μ = Coefficient of friction between the blocks and the drum, θ = Semi-angle of each block subtending at the centre of drum, and n = Number of blocks) T₁/T₂ = [(1 - μ tanθ)/ (1 + μ tanθ)]n T₁/T₂ = (μθ)n T₁/T₂ = [(1 + μ tanθ)/ (1 - μ tanθ)]n T₁/T₂ = μθ × n T₁/T₂ = [(1 - μ tanθ)/ (1 + μ tanθ)]n T₁/T₂ = (μθ)n T₁/T₂ = [(1 + μ tanθ)/ (1 - μ tanθ)]n T₁/T₂ = μθ × n ANSWER DOWNLOAD EXAMIANS APP
Machine Design The connecting rod bolts are tightened up with initial tension greater than the external load so that Bolts are weakest elements Bolts will not loosen during service Joint may not open up The resultant load on the bolt would not be affected by the external cyclic load Bolts are weakest elements Bolts will not loosen during service Joint may not open up The resultant load on the bolt would not be affected by the external cyclic load ANSWER DOWNLOAD EXAMIANS APP
