How does capillary rise affect effective stress in soils?
Effective Stress at Ground Water Table = Total Stress minus the Pore water stress, but the pore water stress is negative, therefore = Total Stress plus the water pressure in capillary zone. -kelvinbrbTSU
What is important of effective stress in soil mechanics?
Effective Stress is the grain to grain contact of soil particles. the higher the effective stress, the stronger the soil. effective stress at a certain depth is calculated as follows: Effective stress = total stress - pore water pressure the pore water pressure is often taken as water table. pore water pressure has a negative effectice on effective stress, as it hinders grain to grain contact.
What stress to consider in stress analysis. true stress or engineering stress?
We almost always use engineering stress as that is the number reported in strength tests.
Is allowable stress design based on elastic analysis or plastic analysis?
elastic design
How is stress analysis on jib cranes done?
A stress analysis on Jib cranes must be done before they can be placed in usage. The analysis consists of mathematical equations considering the length of the crane and maximum load capacity.

How effective is JB Weld in withstanding stress during a stress test?
JB Weld is highly effective in withstanding stress during a stress test, as it is a strong and durable adhesive that can bond various materials together securely.
Why the principle of effective stress important in soil mechanics?
coz at the end of structure construction soil grains are the one whic carry the load so useful in analysis of bearing capacity of granular soil
What is the difference between stress coat and stress coat plus?
The latter is more effective.
Why are slope movements commonly preceded by a decrease in effective stress?
Slope movements are commonly preceded by a decrease in effective stress because there is a direct correlation between effective stress and the strength of a frictional material like soil, whereby as the effective stress decreases, the normal stress on any potential shear surface within the material also decreases. This in turn leads to a reduction in the shear strength of said surface. If this reduces to such an extent that the shear stress on the surface exceeds the frictional shear strength, movement can occur. Further to this, slopes composed of fine grained clay soils will undergo shrink and swell cycles as effective stress changes occur which can lead to strain softening behaviour and progressive failure. For more information see the related link. In particular review the equation in section 3.4 where frictional strength on a theoretical slip surface is shown to be dependent on the total normal stress (sigma n) acting on the surface minus the pore water pressure (u) or in other words the strength is directly proportional to the normal effective stress).
