RCC Structures Design Pick up the incorrect statement from the following. The intensity of horizontal shear stress at the elemental part of a beam section, is directly proportional to Area of the section Moment of the beam section about its neutral axis Shear force Distance of the C.G. of the area from its neutral axis Area of the section Moment of the beam section about its neutral axis Shear force Distance of the C.G. of the area from its neutral axis ANSWER DOWNLOAD EXAMIANS APP
RCC Structures Design In a doubly-reinforced beam if ‘c’ and ‘t’ are stresses in concrete and tension reinforcement, ‘d’ is the effective depth and ‘n’ is depth of critical neutral axis, the following relationship holds good (t + c)/n = (d + n)/n mc/t = n/(d - n) (m + c)/t = n/(d + n) mc/t = (d - n)/t (t + c)/n = (d + n)/n mc/t = n/(d - n) (m + c)/t = n/(d + n) mc/t = (d - n)/t ANSWER DOWNLOAD EXAMIANS APP
