A simply supported rectangular concrete beam of span $8 \mathrm{~m}$ has to be prestressed with a force of $1600 \mathrm{kN}$. The tendon is of parabolic profile having zero eccentricity at the supports. The beam has to carry an external uniformly distributed load of intensity $30 \mathrm{kN} / \mathrm{m}$. Neglecting the self-weight of the beam, the maximum dip (in meters, up to two decimal places) of the tendon at the mid-span to balance the external load should be
