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

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

The connecting rod will be equally strong in buckling about X-axis and Y-axis, if Ixx = 4 Iyy

The most suitable section for the connecting rod is T-section

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

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

The connecting rod will be equally strong in buckling about X-axis and Y-axis, if Ixx = 4 Iyy

Machine Design
Elastic nut is a locking device in which

A slot is cut partly in middle of nut and then slot reduced by tightening a screw

Through slots are made at top and a cotter pin is passed through these and a hole in the bolt, and cotter pin splitted and bent in reverse direction at other end

Hard fibre or nylon cotter is recessed in the nut and becomes threaded as the nut is stewed on the bolt causing a tight grip

One small nut is tightened over main nut and main nut tightened against smaller one by loosening, creating friction jamming
