A cylindrical sample of soil is isotropically compressed under drained condition with a vertical stress of 100 kPa and a radial stress of 100 kPa. Subsequently, the axial stress was held constant and the radial stress was increased to 300 kPa under an un-drained condition.
(a) Create a graph with the x-axis as p, p' and the y-axis as q. Calculate and plot the initial mean effective stress and deviatoric stress
(b) Calculate the increase in mean total stress and deviatoric stress.
(c) Plot the current total and effective stress paths (assume the soil is a linear, isotropic, elastic material).
(d) Determine the slopes of the total and effective stress paths and the maximum excess pore water pressure.
Determine the maximum force (P) that can safely applied to a steel tee section (20 feet in length) with the point loads at 5 feet from each end. Fixed at one end, pin at the other.
For the state of plane stress shown,determine a)principal planes b)principal stresses c) maximum shearing stress and corresponding normal stress
You have just received $10,000 witch which you can do anything. You have decided to invest the money over a long period of time and then use it to make a down payment on a vacation home.
A certain fluid at 15 psia is contained in a cylinder behind a frictionless piston. The initial volume of the fluid is 300 in^3. The fluid expands to a volume of 450 in^3 while the pressure increases to 25 psia
