A small element at the critical section of a component in biaxial state of stress with the two principal stresses being 360 MPa and 140 MPa. The maximum working stress according to distortion energy theory is
-
- 220 MPa
- 110 MPa
- 314 MPa
- 330 MPa
Correct Option: C
According to distorsion energy theorem
f²1 + f²2 - f1 = (Working stress)²
Working stress = √(360)² + (140)² - (360 140)
= 314.32 MOa
