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