Machine Design Which of the following statement is wrong for a connecting rod? If Ixx < 4 Iyy, the buckling will occur about X-axis If Ixx > 4 Iyy, the buckling will occur about Y-axis The most suitable section for the connecting rod is T-section The connecting rod will be equally strong in buckling about X-axis and Y-axis, if Ixx = 4 Iyy If Ixx < 4 Iyy, the buckling will occur about X-axis If Ixx > 4 Iyy, the buckling will occur about Y-axis The most suitable section for the connecting rod is T-section The connecting rod will be equally strong in buckling about X-axis and Y-axis, if Ixx = 4 Iyy ANSWER DOWNLOAD EXAMIANS APP

Machine Design The plasticity is the property of a material which enables it to Resist fracture due to high impact loads Regain its original shape after deformation when the external forces are removed Retain deformation produced under load permanently Draw into wires by the application of a tensile force Resist fracture due to high impact loads Regain its original shape after deformation when the external forces are removed Retain deformation produced under load permanently Draw into wires by the application of a tensile force ANSWER DOWNLOAD EXAMIANS APP
Machine Design A plate with an elliptical hole in the centre, with semi-major axis (a) perpendicular to the direction of loading and semi-minor axis (b) along the direction of loading, is subjected to a pull P. The maximum stress induced at the edge of the hole is equal to (where σ = Stress for a plate with no hole i.e. nominal stress) σ [1 + (b/3a)] σ [1 + (b/2a)] σ [1 + (3a/b)] σ [1 + (2a/b)] σ [1 + (b/3a)] σ [1 + (b/2a)] σ [1 + (3a/b)] σ [1 + (2a/b)] ANSWER DOWNLOAD EXAMIANS APP
