Machine Design The elasticity is the property of a material which enables it to Retain deformation produced under load permanently Regains its original shape after deformation when the external forces are removed Draw into wires by the application of a tensile force Resists fracture due to high impact loads Retain deformation produced under load permanently Regains its original shape after deformation when the external forces are removed Draw into wires by the application of a tensile force Resists fracture due to high impact loads ANSWER DOWNLOAD EXAMIANS APP
Machine Design In designing a sleeve coupling, length of the sleeve is taken as (where d = Diameter of the shaft) 2d + 20 mm d + 17 mm 2d + 13 mm 3.5 d 2d + 20 mm d + 17 mm 2d + 13 mm 3.5 d ANSWER DOWNLOAD EXAMIANS APP
Machine Design If T₁ and T₂ are the tensions on the tight and slack sides of the belt respectively, and Tc is the centrifugal tension, then initial tension in the belt is equal to T₁ - T₂ + Tc T₁ + T₂ + Tc (T₁ - T₂ + Tc)/2 (T₁ + T₂ + Tc)/2 T₁ - T₂ + Tc T₁ + T₂ + Tc (T₁ - T₂ + Tc)/2 (T₁ + T₂ + Tc)/2 ANSWER DOWNLOAD EXAMIANS APP
Machine Design The cracks in helical springs used in railway carriages usually start on the inner side of the coil because of the fact that It is more stretched than the outer side during the manufacturing process It is subjected to a higher cyclic loading than the outer side It has a lower curvature than the outer side It is subjected to a higher stress than the outer side It is more stretched than the outer side during the manufacturing process It is subjected to a higher cyclic loading than the outer side It has a lower curvature than the outer side It is subjected to a higher stress than the outer side ANSWER DOWNLOAD EXAMIANS APP
