For the following questions answer them individually
If the average bending stress is 6 kg/cm2
for M 150 grade concrete, the length of embedment of a bar of diameter d according to I.S. 456
specifications is
A singly reinforced concrete beam of 25 cm width and 70 cm effective depth is
provided with 18.75 cm2
steel. If the modular ratio (m) is 15, the depth of
the neutral axis, is
If the neutral axis of a T-beam is below the slab, the relationship between the
flange width B, depth of neutral axis n, thickness of the slab $$d_s$$, effective depth of the
beam d, gross area of tensile steel $$A_t$$ and the modular ratio m may be stated as
In a combined footing if shear stress exceeds 5 kg⁄cm2, the nominal stirrups
provided are
To ensure that the hogging bending moment at two points of suspension of a pile
of length L equals the sagging moment at its center, the distance of the
points of suspension from either end is
To have pressure wholly compressive under the base of a retaining wall if width
b, the resultant of the weight of the wall and the pressure exerted by the
retained, earth should have eccentricity not more than
The ratio of the length and diameter of a simply supported uniform circular beam
which experiences maximum bending stress equal to tensile stress due
to same load at its mid span is
The ratio of the deflections of the free end of a cantilever due to an isolated load
at $$\frac{1}{3}^{rd}$$ and $$\frac{2}{3}^{rd}$$ of the span is
