A simply supported beam, 300 mm x 600 mm in dimension as shown in Figure 2, is prestressed by a straight tendon with a force 1000 KN. Situational Problem 11: Locate the position of the lower kern point, in mm. Situational Problem 12: Assuming the tendons are placed at the lower kern point as derived from Situational Problem 11, determine the extreme concrete fiber stresses at the top (in kN/m²) due to the prestressing force of 1000 KN. Situational Problem 13: Assuming the tendons are placed at the lower kern point as derived from Situational Problem 11, determine the extreme concrete fiber stresses at the bottom (in kN/m²) due to the prestressing force of 1000 kN.
