engineering recuitment AAI JE Technical Mock Test 2020-21 Strength of Materials Principal Stress or Strain Graphical Method of Analysis
If σ1 and σ3 are the algebraically largest and smallest principal stresses respectively, the value of the maximum shear stress is
1
\(\frac{{{{\rm{\sigma }}_1} + {{\rm{\sigma }}_3}}}{2}\)
2
\(\frac{{{{\rm{\sigma }}_1} - {{\rm{\sigma }}_3}}}{2}\)
3
\(\sqrt {\frac{{{{\rm{\sigma }}_1} + {{\rm{\sigma }}_3}}}{2}}\)
4
\(\sqrt {\frac{{{{\rm{\sigma }}_1} - {{\rm{\sigma }}_3}}}{2}} \)
