At a point, the normal and shear stresses acting on one plane are 8,000 psf compression and 2,000 psf, respectively. On a perpendicular plane, the normal and shear stresses are 2,000 psf compression and 2,000 psf, respectively.

(a) Draw the Mohr’s circle.

(b) Determine the value of the principal stresses.

(c) Find the angle between the plane on which the 8,000 psi compressive stress acts andthe major principal plane.

(d) What is the maximum shear stress acting at the point?
