Machine Design When the shaft rotates in anticlockwise direction at high speed in a bearing, it will Move towards left of the bearing making metal to metal contact Have contact at the bottom most of the bearing Move towards right of the bearing making metal to metal contact Move towards right of the bearing making no metal to metal contact Move towards left of the bearing making metal to metal contact Have contact at the bottom most of the bearing Move towards right of the bearing making metal to metal contact Move towards right of the bearing making no metal to metal contact ANSWER DOWNLOAD EXAMIANS APP
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 = μθ × n T₁/T₂ = (μθ)n T₁/T₂ = [(1 + μ tanθ)/ (1 - μ tanθ)]n T₁/T₂ = [(1 - μ tanθ)/ (1 + μ tanθ)]n T₁/T₂ = μθ × n T₁/T₂ = (μθ)n T₁/T₂ = [(1 + μ tanθ)/ (1 - μ tanθ)]n T₁/T₂ = [(1 - μ tanθ)/ (1 + μ tanθ)]n ANSWER DOWNLOAD EXAMIANS APP
Machine Design A shaft is subjected to a maximum bending stress of 80 N/mm² and maximum shearing stress equal to 30 N/mm² at a particular section. If the yield point in tension of the material is 280 N/mm² and the maximum shear stress theory of failure is used, then the factor of safety obtained will be 2.8 3.5 3 2.5 2.8 3.5 3 2.5 ANSWER DOWNLOAD EXAMIANS APP

Machine Design A closely coiled helical spring is acted upon by an axial force. The maximum shear stress developed in the spring is τ. The half of the length of the spring if cut off and the remaining spring is acted upon by the same axial force. The maximum shear stress in the spring in new condition will be τ/2 4 τ 2 τ τ τ/2 4 τ 2 τ τ ANSWER DOWNLOAD EXAMIANS APP
