Asap need right complete solution !!!
A pre-stressed hollow core slab has property as follows: A - 100,814 mm2, St - Sb - 4,111,587 mm3. The slab is prestressed with 460 KN force at an eccentricity, e-40 mm below the centroid of the section. The weight of the slab is 3.23 kPa, SDL is 2.8 kPa, and live load is 28 kPa. The slab is simply supported on bearings at L-8.5m. Allowable stresses at service loads are 3.1 MPa in tension and 19.6 MPa in compression. Consider 20% loss of prestress at service loads. Determine the resulting stress at the bottom fibers of the slab at L/4 from the center of bearings, in MPa Do not round-off during the course of solving. Answer in two decimal places. O O 150 mm 1.2m
