engineering recuitment BHEL Engineer Trainee Mock Test 2025 Strength of Materials Principal Stress or Strain
The 2D stress at a point is given by the matrix \(\left[ {\begin{array}{*{20}{c}} {{{\rm{\sigma }}_{{\rm{xx}}}}}&{{{\rm{\tau }}_{{\rm{xy}}}}}\\ {{{\rm{\tau }}_{{\rm{xy}}}}}&{{{\rm{\sigma }}_{{\rm{yy}}}}} \end{array}} \right] = \left[ {\begin{array}{*{20}{c}} {50}&{15}\\ {15}&{10} \end{array}} \right]{\rm{MPa}}\)
The maximum shear stress in (MPa) units is:
1
55
2
45
3
