Saturation= Vw/Vv

if soil is in dry state then there will be no water hence Be became 0 ,therefore saturation is 0.

if the voids of soil is totally filled by water then Vw=Vv, hence S=1

so it ranges between 0 to 1

if soil is in dry state then there will be no water hence Be became 0 ,therefore saturation is 0.

if the voids of soil is totally filled by water then Vw=Vv, hence S=1

so it ranges between 0 to 1

Sum of moment at point A=0

therefore Mo= Rb*l

Rb= Mo/l

similarly sum of moment at point B =0

Ra= Mo/l

therefore Mo= Rb*l

Rb= Mo/l

similarly sum of moment at point B =0

Ra= Mo/l
