RCC Structures Design With usual notations the depth of the neutral axis of a balanced section, is given by t/mc = (d + n)/n t/mc = (d - n)/n mc/t = n/(d - n) mc/t = (d - n)/n t/mc = (d + n)/n t/mc = (d - n)/n mc/t = n/(d - n) mc/t = (d - n)/n ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design The modular ratio ‘m’ of a concrete whose permissible compressive stress is ‘C’, may be obtained from the equation. m = 3500/3C m = 2800/3C m = 700/3C m = 1400/3C m = 3500/3C m = 2800/3C m = 700/3C m = 1400/3C ANSWER DOWNLOAD EXAMIANS APP
