Arectangular concrete beam of width 300 mm and depth 750 mm is post-tensioned by applyin a jacking force of 900 kN to a single tendon which is placed with a positive eccentricity of 25 mm measured vertically (downwards) from the centre of the beam. The dimension of the cable anchorage is 250 mm (vertical) by 150 mm (horizontal). Calculate the vertical bursting force behind the anchorage. Note: Do not forget to check whether it is the case of high eccentricity or low eccentricity.
