1. It is a method of applying pre-compression to control the stresses resulting due to external loads below the neutral axis of the beam. a. Prestressed Concrete b. Pre-Compression c. Pre-Tension d. Post Tension 2. In this method the concrete is prestressed with tendons before it is placing in position a. b. Prestressed c. Pre-Tensioning d. Post-Tensioning e. None of the above 3. In this method prestressing is done after the concrete attains its strength a. Prestressed Concrete b. Pre-Tensioning c. Post Tensioning d. None of the above 4. A rectangular concrete beam of 250 mm wide and 600 mm deep is prestressed by means of fours 10 mm diameter high tensile bars located at 200 mm from the soffit of the beam. If the effective stress in the wires is 500 N/mm2. What is the maximum bending moment that can be applied to the section without causing tension at soffit of the beam?? a. O b. 24.5 kN.m c. 26.5 kN.m d. 31.5 kN.m e. 38.5 kN.m
