There is a post-tensioned prestressed concrete beam with effective simply supported span of 8 m. This beam with rectangular cross section is prestressed with parabolic cable with 200 kN force, having eccentricity 200 mm above neutral axis at mid-span and 200 mm below it at support. The cable can be replaced by an equivalent effect as
