Hey
Im a final yr degree student .
Loading (KN)
4kN 5kN 6kN 7kN
Depth
100 2.5 2.3 2.4 2.5
150 2.9 2.5 2.7 2.8
200 2.6 2.7 2.4 2.2
250 2.7 2.7 2.7 2.7

The Left Hand Column contains the Depth of the Slab Required in mm
The Top Row is The MAX Loading Applied in Kn
The internal values are the distance the slab must span in metres

My problem is that if I were to pick a load value of 6kn over a slab
distance of 2.6m then i would like it to return the corresponding slab depth;
in this case 150mm or 250mm is sufficent. Similarily if i was to choose a
load of 7Kn and a slab span of 2.8m then it would return a depth value of
150mm
