Question 1

Four vertical loads are applied on a point A, B, C and D with a magnitude 400, 200, 400 and 1200KN at a distance of 60, 120, 180 and 240m horizontally respectively from a left support in a cable supported between two point separated between 300m apart horizontally, with the right support being 12m higher than the left support. The largest sag in the cable will be found at which point.

Question 2

The truss shown in figure is

Question 3

1) Carry over factor is always 0.5 for a fixed support.
2) Carry over factor can also be greater than 1.
3) Moment distribution method is based on stiffness approach.
4) In linear elastic structure, the minimum potential energy leads to compatibility condition.
