Problem $4$

A sample of a dry, coarse$-$grained material of mass $500$ grams was shaken through a nest of sieves, and the following results were as given in the table below.

a$)$ Plot the particle size distribution $($gradation$)$ curve.

b$)$ Determine $(1)$ the effective size, $(2)$ the average particle size, $(3)$ the uniformity coefficient, and $(4)$ the coefficient of curvature.

c$)$ Determine the textural composition of the soil $($the amount of gravel, sand, etc.$).$
