Problem 19.2 After failures occurred in several cast-iron bearing housings an engineering testing team used strain gage rosettes (future topic in this course) to determine operating stresses. Through testing they determined the point where failure initiated and measured strain at that location. They then calculated the stresses evidently present at that point to be gx = 0 MPa, Q=115 MPa, xx= 75 MPa. The material has been characterized by a uniaxial test that resulted in ult=170 MPa and cult=655 MPa. Use an appropriate failure theory to affirm the findings that this state of stress is very near the theoretical fracture capacity of the material.
