RCC Structures Design ‘P’ is the pre-stressed force applied to tendon of a rectangular pre-stressed 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 f = (A/P) - (M/Z) f = (P/A) - (M/6Z) f = (P/'- (Z/M) f = (P/A) - (M/Z) f = (A/P) - (M/Z) f = (P/A) - (M/6Z) f = (P/'- (Z/M) f = (P/A) - (M/Z) ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design Pick up the incorrect statement from the following: Tensile reinforcement bars of a rectangular beam Are curtailed if not required to resist the bending moment Are maintained at bottom to provide at least local bond stress Are bent up at suitable places to serve as shear reinforcement Are bent down at suitable places to serve as shear reinforcement Are curtailed if not required to resist the bending moment Are maintained at bottom to provide at least local bond stress Are bent up at suitable places to serve as shear reinforcement Are bent down at suitable places to serve as shear reinforcement ANSWER DOWNLOAD EXAMIANS APP
