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

A. Shear force

B. Area of the section

C. Distance of the C.G. of the area from its neutral axis

D. Moment of the beam section about its neutral axis

A. Compression is borne entirely by concrete

B. Steel possesses initial stresses when embedded in concrete

C. Plane sections transverse to the centre line of the beam before bending remain plane after bending

D. Elastic moduli for concrete and steel have different values within the limits of deformation of the beam

A. Is greater than the depth of critical neutral axis, the concrete attains its maximum stress earlier

B. Is less than the depth of critical neutral axis, the steel in the tensile zone attains its maximum stress earlier

C. Is equal to the depth of critical neutral axis; the concrete and steel attain their maximum stresses simultaneously

D. All the above
