Скачать или смотреть Soil mechanics MCQS | Chapter 1 | DAE civil Technology

In this video series, the multiple-choice questions of the first chapter of the soil mechanics book from DAE civil technology are solved in detail..
The following MCQs have been discussed.
1. Size of the gravel defined in mm as
a) 4.75 – 76.2
b) 0.20 – 4.75
c) 0.002 – 0.20
d) 76.2 – 102.5
2. Size of the gravel defined in mm as
a) 4.75 – 76.2
b) 0.20 – 4.75
c) 0.002 – 0.20
d) 76.2 – 102.5
3.Void ratio ''e'' is determined in soil sample by
e= Vv/V
e= Vv/Vs
e = V-Vs
e = Vd - Vs
4. Porosity ''n'' is determined in soil sample by
n= Vv/V
n= Vv/Vs
n = V-Vs
n = Vd – Vs
5. Relation Between void ratio and porosity is expressed as
e = n/(1-n)
e = n/(n-1)
e = (n-1)/n
n = e/(1+e)
6. Relation between porosity and void ratio is expressed as
n = e/(1-e)
n = e/(e-1)
n = (e+1)/e
n = e/(1+e)
7. Degree of saturation is expressed as
A. S= Vv/Vs
B. S= Vv/Vw
C. S= Vw/Vv
D. S= Vw/Vs
8. Dry density is expresses by
A. rd= wd/V
B. rd= Ws/V
C. rd= Ws/Vs
D. rd= Vs/Ws
9. Dry density of soil mass is expressed by
A. rd= (1+m )/r
B. rd= (1-m)/r
C. rd= r/(1+m)
D. rd= r/(1-m)
10. Moisture content in a soil sample is expressed by
A. m= Ww/Wd
B. m= Ww/W
C. m= Ww/Wd
D. m = W/Ww
