As per Indian Railway Board, the impact factor i (also known as coefficient of dynamic augment, CDA) in steel girders for single track span is
2.
Which of the following types of failures occur in the beam-column connections?
1. Failure by lateral-torsional buckling
2. Failure by combined instability in both the principal directions
3. Failure by combined twisting and bending on the torsionally weak sections
4. Failure by combined twisting and bending when plane of bending does not contain the shear centre

A cable carrying a load of 10 kN/m run of horizontal span is stretched between supports of 100 m apart. If the supports are at same level and central dip of 8 m, the ratio of greatest and least tensions in the cable will
