A few important questions have been put forwarded to you in the script and the rest you can watch the YouTube video. Please like, share, comment, and Subscribe my channel in youtube and this website also. The questions are as follows:
Q2: What is the difference between engineering stress and true stress?
Ans: According to biology, Stress is something that disrupts homeostasis(the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes.) of an organism. In engineering, Stress is an
external applied force that pushes, pulls, twists, or otherwise puts force on something.
Engineering stress assumes that the area a force is acting upon remains constant, true stress takes into account the reduction in area caused by the force.
Q7. What are the reasons for geotechnical site investigations?
A: The reasons for the geotechnical site investigation is to know the soil properties, in so doing be in position to determine whether the Particular site is
suitable for the purpose intended to know the history of the site
To know what remedies need to be put in place before construction can start
Based on the soil properties, that can be determined on site and in the lab, design the appropriate foundation for the structure.
Q5: Why does the pressure increase under soil?
Ans: The Soil pressure increases with the increase in depth due to the overburden or self-weight of the soil and due to loadsimposed upon the soil.
Eg: the pressure variation below the depth of soil is linear and the relation is given by pressure
= unit weight x depth.
Which means as the depth increases, there will be a
linear increase in the soil pressure.
