PROBLEM 7.82 - 100 MPa Solve Prob. 7.81, using the maximum-shearing-stress criterion. PROBLEM 7.81 The state of plane stress shown occurs in a machine component made of a steel with oy = 325 MPa. Using the maximum-distortion-energy criterion, determine whether yield will occur when (a) o = 200 MPa, (b) o = 240 MPa, (C) 00 = 280 MPa. If yield does not occur, determine the corresponding factor of safety.

P12.026
The stresses shown act at a point on the free surface of a
machine component. Normal and shear stress magnitudes acting on
horizontal and vertical planes at the point are
Sx = 17.9 ksi, Sy = 2.3
ksi, and Sxy = 7.4 ksi. Assume β=30∘. Determine
the normal stresses σx and σy and the shear stress τxyat the
point.
