Question

'$p_1$' and '$p_2$' are two equal tensile principal stresses. On the plane AB inclined at 45° to the plane of '$p_1$' as shown in the figure below

• A. the shear stress is maximum
• B. the normal stress is zero
• C. the shear stress is zero
• D. the normal stress is maximum

Answer 1

The correct option is C the shear stress is zero

$Shearstress=\frac{p_1-p_2}{2}=0as{p}_1=p_2$
