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 + (2a/b)]
σ [1 + (3a/b)]
σ [1 + (b/2a)]

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

The most suitable section for the connecting rod is T-section
If Ixx < 4 Iyy, the buckling will occur about X-axis
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
