Question

why should we care for stress and particularly in situ stress in rock mechanics and engineering sometimes if not always?

Answer 1

Answer:

Rock Mechanics

Study of the mechanical behaviour of Rocks and their mass.

This study will provide us to weather to use the rock for construction purpose or not.

For example we are using ballast in case of railway tracks and foundation stones etc.,

Insitu Stress:

​​​​​Among various properties Insitu Stress is one of the major factor we should consider.

It is a local stress which is due to the formation of rock mass at a particular point.

Magnitude and direction vary with in geological system.

This parameter gives us clarity about strength of rock and helps to design load carrying capacity of a particular rock.
