The state of stress at a point consists of a major principal stress of 10,000 psf and a minor principal stress of 5,000 psf. The major principal stress acts in the vertical direction. (a) Draw the Mohr's circle of stress and show the pole point (origin of planes). (b) Determine the maximum shear stress. (c) Determine the normal stress and shear stress on a plane that makes an angle of 60 degree with the minor principal plane.
