engineering recuitment HPCL Engineer Mock Test 2024 Strength of Materials Principal Stress or Strain
A point on a machine component has the following state of plane strain:
εxx = (-) 720 μ, εyy = (-) 400 mu, εxy = 660 mu, (μ = 10-6)
If E = 70 GPa and G = 28 GPa, then the three principal stresses (σ1, σ2, σ3 in MPa) are
1
-42.18, -83.26, 0
2
-71.68, -53.76, 0
3
-42.18, -83.26, -31.36
4
42.18, 83.26, 31.36
