A prestressed concrete beam has the following characteristics: a width of 300mm overall depth of 600mm prestressing tendons are placed at a distance “e” below the NA of the beam the applied prestressing force is P in kN there is 15% loss of prestress 3. Find e ( up to 2 decimal places ) in mm when the compressive stresses at the top and bottom of the beam are 2MPa and 12Mpa, respectively.
