Stress & Strain
GATE 2017
Easy
The state of stress at a point is σx=σy=σz=τxz=τzx=τyz=τzy=0 and τxy=τyx=50 MPa. The maximum normal stress (in MPa) at that point is __________.
50 MPa(± 0.5 accepted)
Explanation
This is a state of pure shear. The principal (normal) stresses for pure shear τxy are ±τxy, so the maximum normal stress equals the shear stress magnitude, 50 MPa.
