A prestressed concrete beam with parabolic tendon is shown in figure below. The effective prestressing force at service load is 1480 kN. There is a central concentrated load of 250 kN acting on the beam. If the self-weight of beam is excluded, then the stress on the top fibre at the midspan is - (in MPa, upto one decimal place).
