Stress & Strain
GATE 2018
Easy
If σ1 and σ3 are the algebraically largest and smallest principal stresses respectively, the value of the maximum shear stress is
- A(σ1+σ3)/2
- (σ1−σ3)/2
- C√((σ1+σ3)/2)
- D√((σ1−σ3)/2)
Explanation
The maximum shear stress at a point equals half the difference between the largest and smallest principal stresses: τmax = (σ1−σ3)/2.
