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/Z) f = (P/A) - (M/6Z) f = (P/'- (Z/M) f = (A/P) - (M/Z) f = (P/A) - (M/Z) f = (P/A) - (M/6Z) f = (P/'- (Z/M) ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If ‘p’ is the net upward pressure on a square footing of side ‘b’ for a square column of side ‘a’, the maximum bending moment is given by M = pb (b + a)/8 M = pb (b - a)²/4 M = pb (b - a)²/8 M = pb (b + a)/8 M = pb (c - a)/4 M = pb (b + a)/8 M = pb (b - a)²/4 M = pb (b - a)²/8 M = pb (b + a)/8 M = pb (c - a)/4 ANSWER DOWNLOAD EXAMIANS APP
