Compaction is due to

Solution:

Soil compaction occurs when soil particles are pressed together, reducing pore space between them. Heavily compacted soils contain few large pores, less total pore volume and, consequently, a greater density. A compacted soil has a reduced rate of both water infiltration and drainage. This happens because large pores more effectively move water downward through the soil than smaller pores.

QUESTION: 100

If the deflection at the free end of a uniformly loaded cantilever beam of length 1 m is equal to 7.5 mm, then the slope at the free end is 

Solution:

Deflection of a cantilever beam for uniform load is given by:

δmax= WL4/8EI

While the slope at the free end is given by:

θmax=WL3/6EI

Taking ratio of these two equations we get,

(WL4/8EI)/(WL3/6EI)=7.5/θmax

⇒6*1000mm/8=7.5/θmax

θmax=0.01 radian.
