![A prestressed concrete rectangular beam has a
width = 400 mm and a depth 900 mm. It is
simply supported over a span length of 12m.
The beam is subjected to a prestressing force
of 2000 KN using a parabolic cable profile
having an eccentricity of 240 mm at mid span
and zero eccentricity at the supports. Calculate
the minimum dead load moment including the
self weight and the corresponding maximum
possible live load moment at the centre span
of the beam at service load, if the service load
stress in the beam should be never tensile.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4b6cfcbf-b208-40bc-bd12-982fd5334da8%2F4a90aab9-f398-40cc-ab67-51bdc8745c96%2Fumeqxd9_processed.jpeg&w=3840&q=75)
