Question

The shear strength of a soil (a) is directly proportional to the angle of internal friction of the soil (b) is inversely proportional to the angle of internal friction of the soil (c) decreases with increase in normal stress (d) decreases with decrease in normal stress

Answer 1

HEY MATE HERE IS YOUR ANSWER

(d) Decrease with decrease in normal stress.

Answer 2

The answer to this question is option D, and it can be rewritten as “The shear strength of soil decreases with a decrease in normal stress.”

This is governed by the rules of soil mechanics and is required for soil exploration work required for doing the proper foundation work.

It is a part of civil engineering.
