Which of the following statement is wrong for a connecting rod?

If Ixx < 4 Iyy, the buckling will occur about X-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 Y-axis

If Ixx < 4 Iyy, the buckling will occur about X-axis
