Answer:
correct option is (A) 0.5
Explanation:
given data
axial column load = 250 kN per meter
footing placed = 0.5 m
cohesion = 25 kPa
internal friction angle = 5°
solution
we know angle of internal friction is 5° that is near to 0°
so it means the soil is almost cohesive soil.
and for a pure cohesive soil
= 0
and we know formula for is
= (Nq - 1 ) × tan(Ф) ..................1
so here Ф is very less should be nearest to zero
and its value can be 0.5
so correct option is (A) 0.5
Answer:
beam with a span length of 10 ft, a width of 8 in, and an effective depth of 20 in. Normal weight concrete is used for the beam. This beam carries a total factored load of 9.4 kips. The beam is reinforced with tensile steel, which continues uninterrupted into the support. The concrete has a strength of 4000 psi, and the yield strength of the steel is 60,000 psi. Using No. 3 bars and 60,000 psi steel for stirrups, do the followings:
Answer:
you need more details but if you have to find the difference, its $2.00
Explanation:
8-6=2
Answer:
The density of the copper is higher than aluminium. Hence it is heavier compared to aluminium conductors it requires strong structures and hardware to bear the weight. More ductile and has high tensile strength.

Answer:
C). Inorganic Chemistry
Explanation:
Inorganic chemistry is characterized as the branch of chemistry that deals with the elements(including carbon) and those compounds which do not contain carbon includes minerals, metals, inorganic, organometallic compounds. As we know, <u><em>'Silicone' is characterized as a semi-inorganic polymeric compound</em></u> that possesses a wide range of thermal stability and extreme water repellence. Thus, it is classified as a part of inroganic chemistry. Hence, <u>option C</u> is the correct answer.
