The Mohr's circle of plane stress for a point in a body is shown. The design is to be done on the basis of the maximum shear stress theory for yielding. Then, yielding will just begin if the designer chooses a ductile material whose yield strength is
-
- 45 MPa
- 50 MPa
- 90 MPa
- 100 MPa
Correct Option: C
Applying maximum shear stress theory
| τmax = | = | 2 | 2 |
σY.P. = σx – σy = –100 –(–10)
= –90 MPa
