properties of soil that will have a direct
impact on the design of structures to be built
on it

Answer 2

soil mechanics

Question 3

• the branch of mechanics concerned
  w/ the response of rock to the loads applied
  into it

Answer 3

rock mechanics

Question 4

theory that states that all strains
created by externally applied loads are
instantaneously and totally recoverable
upon removal of all external loads.

Answer 4

theory of elasticity

Question 5

theory that states that When
rock mass will be under the action of large
enough stresses, there is strain permanent
deformations which remain after the removal
of the externally applied load

Answer 5

theory of plasticity
