RCC Structures Design The modular ratio ‘m’ of a concrete whose permissible compressive stress is ‘C’, may be obtained from the equation. m = 700/3C m = 1400/3C m = 3500/3C m = 2800/3C m = 700/3C m = 1400/3C m = 3500/3C m = 2800/3C ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The maximum shear stress (q) in concrete of a reinforced cement concrete beam is (Shear force × Width)/Lever arm Shear force/(Lever arm × Width) Lever arm/(Shear force × Width) Width/(Lever arm × Shear force) (Shear force × Width)/Lever arm Shear force/(Lever arm × Width) Lever arm/(Shear force × Width) Width/(Lever arm × Shear force) ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design If K is a constant depending upon the ratio of the width of the slab to its effective span l, x is the distance of the concentrated load from the nearer support, bw is the width of the area of contact of the concentrated load measured parallel to the supported edge, the effective width of the slab be is K/x (1 + x/d) + bw Kx (1 - x/l) + bw All listed here Kx (1 + x/l) + bw K/x (1 + x/d) + bw Kx (1 - x/l) + bw All listed here Kx (1 + x/l) + bw ANSWER DOWNLOAD EXAMIANS APP
