Textbook Question
Chapter 10, Problem 10.1CTP
EB and FG are two planes inside a soil element ABCD as shown in Figure 10.50.
Stress conditions on the two planes are
Plane EB: σEB = 25 kN/m2; τEB = +10 kN/m2
Plane FG: σFG = 10 kN/m2; τFG = –5 kN/m2
(Note: Mohr’s circle sign conventions for stresses are used above)
Given α; = 25°, determine:
- a. The maximum and minimum principal stresses
- b. The angle between the planes EB and FG
- c. The external stresses on planes AB and BC that would cause the above internal stresses on planes EB and FG
