Question

For the stress state (in MPa) shown in the figure, the major principal stress is 10 MPa.




The shear stress $\tau$ is

• A. 10.0 MPa
• B. 5.0 MPa
• C. 2.5 MPa
• D. 0 MPa

Answer 1

The correct option is B 5.0 MPa

${\sigma }_x=5$
${\sigma }_y=5$

$10=\frac{5+5}{2}+\sqrt{(0{)}^2+{\tau }^2}$
$\Rightarrow \tau =5$ Ans.
