(d) A concrete beam AB of span 12 m is post-tensioned by a cable which is concentric at supports A and B and has an eccentricity of 200 mm in the mid-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 wire if the stress at B is to be 1000 N/mm²? Assume the coefficient of friction between the cable duct and concrete as 0.55 and the friction coefficient for the wave effect as 0.0015/m.
