![13. The major and minor principal stresses acting at a point are 80 psi compression and
20 psi tension.
(a) Draw the Mohr's circle for this stress combination.
(b) What is the maximum shear stress acting at the point, and what value of normal
stress acts on the plane?
(c) Determine the value of the shear and normal stress acting on a plane that is 30°
from the major principal plane.
14. At a point, the normal and shear stresses acting on one plane are 8000 psf compression
and 2000 psf, respectively. On a perpendicular plane, the normal and shear stress
combination is 2000 psf compression and 2000 psf.
(a) Draw the Mohr's circle.
(b) Determine the value of the principal stresses.
(c) Find the angle between the plane on which the 8000 psf compressive stress acts
and the major principal plane.
(d) What is the maximum shear stress acting at the point?
4. The normal and shear stresses acting on one plane passing through a point in a soil
mass are 120 psi compression and 25 psi, respectively. On an orthogonal plane the
stresses are 40 psi compression and 25 psi.
(a) Draw the Mohr's circle for this stress condition.
