A concrete beam AB of span 16 m is post-tensioned by a cable which is concentric at supports A and B and has an eccentricity of 300 mm in the one-third span with a linear variation towards the supports. If the cable is tensioned at the jacking-end A, what should be the jacking stress in the wires if the stress at B is to be 65 MPa. Assume the coefficient of friction between the cable duct and concrete as 0.56 and the wobble friction coefficient as 0.0018/m.
