i want answer?

Update:

The cross-section of a symmetrical I-section prestressed beam is 300 mm by 750 mm (overall), with flanges and web 100 mm thick. The beam is post- tensioned by cables containing 48 wires of 5 mm diameter high-tensile steel wires at an eccentricity of 250 mm. The 28-day strength of concrete in compres- sion is 40 N/mm² and the ultimate tensile strength of wires is 1700 N/mm². Assuming that the grouting of the tendons is 100 per cent effective, determine the ultimate moment of the section.

    You don't know if you want an answer?  Then why you you write all this drivel?  In case you weren't aware, this forum isn't a free service to do your homework for you.  That would be slavery.  We all want a set wage, benefits, a union, etc.
