When the gauge distance is larger than the pitch, the failure of the section may occur in a zig-zag line
When the gauge distance is smaller than the pitch, the failure of the section may occur in a straight right angle section through the centre of rivet holes
When the gauge distance and pitch are both equal, the failure to the section becomes more likely as the diameter of the holes increases
