If water is seeping, the effective stress at any point in a soil
mass will be different from the static case. It will decrease or
increase depending on the direction of seepage. With help of
sketches, describe what will happen to effective stress if the
water is seeping downward through a soil layer.
when soil has undergone adequate drainage, the effective stress is
better then the total stress for determining potential failure or
settlement of the soil.
true or false
Discuss the effect of void ratio, particle size distribution,
and effective stress on soil behaviors (e.g., hydraulic
conductivity, deformation and strength) respectively.
Bonus (10%) Explain your understanding of effective Stress
concepts. Why effective stress is considered the most important
concept in geotechnical engineering including but not limited to
slope engineering, design of earth structures and foundation
engineering, etc.? How did you make the best
understanding and application of effective stress to soil
engineering? (Note: You have calculated them in your homework jobs
assignment and have been applying them in settlement analysis as in
the tests).
What is the importance of having an effective compliance and
ethics program with respect to the FCPA? What is the role of
confidential reporting and internal investigations in the
compliance program?
What is the gravimetric water content, of a soil sample having a
wet mass of 1.63 kg and a dry mass of 1.33 kg? And then answer,
what is the volumetric water content of this sample if its
dimensions are known to be 0.1m x 0.1m x 0.1m?
Please show workings and explain each step.
this is a FEM question.
1a. Describe the procedure for calculating the maximum stress
for a quick heating of a machine.
1b. Suppose we have a vibrating machine component and that we know
the size and frequency of the interference. Explain how we can
calculate the maximum stress in the vibrating machine
component.
