Question

Can you determine the active thrust from a saturated clay sample from the effective friction angle (ϕ’)?

If yes, describe the calculation procedure.

If no, explain why, and suggest a suitable method.

Answer #1

The statement is contradictory as for saturated clay there are both soil parameters, effective cohesion and effective angle of internal friction . So the active thrust can be determined from both angle of internal friction and cohesion as

Therefore the answer will be Yes.

Can the effective friction angle (ϕ’) be used to determine the
active thrust from a saturated clay? describe the calculation
procedure if possible. unless, state a suitable method.

Using the data in Textbook Problem 8.8:
a. Plot the vertical effective consolidation stress versus void
ratio on both arithmetic and semi-log graphs. For the arithmetic
graph, constrain the vertical axes to 0.55 and 0.95; and the
horizontal to 0 to 1,500 kPa; for the semi-log graph, use the same
vertical axis constraints, but use 10 kPa and 10,000 kPa to ease
interpretation. Plot the data points only, and draw in a smooth
curve by hand. Plot each graph on...

Researchers wondered if there was a difference between males and
females in regard to some common annoyances. They asked a random
sample of males and females, the following question: "Are you
annoyed by people who repeatedly check their mobile phones while
having an in-person conversation?" Among the
517517
males surveyed,
168168
responded "Yes"; among the
545545
females surveyed,
204204
responded "Yes." Does the evidence suggest a higher proportion
of females are annoyed by this behavior? Complete parts (a)

1. A city official claims that the proportion of all commuters
who are in favor of an expanded public transportation system is
50%. A newspaper conducts a survey to determine whether this
proportion is different from 50%. Out of 225 randomly chosen
commuters, the survey finds that 90 of them reply yes when asked if
they support an expanded public transportation system. Test the
official’s claim at α = 0.05.
2. A survey of 225 randomly chosen commuters are asked...
