Question

An axially loaded bar is subjected to a normal stress of 173 MPa. The shear stress in the bar is

• A. 75 MPa
• B. 86.5 MPa
• C. 100 MPa
• D. 122.3 MPa

Answer 1

The correct option is B 86.5 MPa

Normal stress,

${\sigma }_1=173$ MPa
${\sigma }_3=0$
Shear stress
$\tau =\frac{{\sigma }_1-{\sigma }_3}{2}=\frac{173}{2}=86.5MPa$
