A wide flange is used as a beam that is simply supported at its ends.The properties are shown.
A = 19600 mm².
by = 229 mm
L = 1249 x10^4mm
te=14 mm
Tx = 25.4 mm
tr = 24.9 mm
ly = 49.5 x10^4mm
d = 623 mm
Ty = 50.5 mm
If the beam is laterally supported at supports only, determine the allowable bending stress for a length of;
1. 2m
2. 4m
3. 6m
4. 8m
