engineering recuitment UPCL AE (E&M) 2021 Mock Test Strength of Materials Principal Stress or Strain
At a point in a strained material, tensile stress of 100 MPa and compressive stress of 60 MPa are found to be principal stresses. Maximum shear stress at that point is:
1
60 MPa
2
20 MPa
3
40 MPa
4
80 MPa
