Question: A simply support beam is 2 5 0 m m 6 0 0 m m in section and has a span of 1 0 m

A simply support beam is 250mm600mm in section and has a span of 10 m is prestressed with parabolic cable which has a maximum eccentricity 100 mm at midspan and minimum eccentricity 20 mm at-support. Effective pre stressing force in the cathle is 350 kN . The beam-carries all inclusive UDLL of 30kNm. Determine principal tension at 0.6 m from the left support and 20 mm above the centroidal axis.
