 P: 1 Can any one help me to find the answer,,, its a very difficult question!!!! Q- calculate the safe inclusive UDL for a 356x171 UB67 simply supported at the ends of span of 9m. The permissible bending stress is 167N/mm*2 and the defluction must not exceed (1/360) x span, and I = 187.2x10*6mm*4 ............. please i need any1 to explain to me..
 P: 143 What does Q- mean? What does UDL mean? What are the units for 356x171? What does UB67 mean? Defluction? You mean Deflection? "please i need any1 to explain to me.." A bit more legwork on your part would go a long way toward getting others to help you.

It's not difficult if you are allowed to use tables for the max deflection and max moment in a simple beam under a uniformly distributed load. Then you need to show some attempt to determine the UDL based on the controlling allowable stress or deflection.

Q- is that it is the question.
