1. P is the prestressed force applied to tendon of a rectangular prestressed beam whose area of cross section is A and sectional modulus is Z. The minimum stress f on the beam subjected to a maximum bending moment M is
3. If permissible compressive stress in concrete is 50 kg/cm2, tensile stress in steel is 1400 kg/cm2 and modular ratio is 18, the depth d of the beam, is
10. The zone in which transverse bending is likely to occur may be obtained by drawing a line from the faces of the column making an angle ?° with horizontal where ?° is
