Physics · Mechanics of Solids
When a body is subjected to a direct tensile stress (σ) in one plane accompanied by a simple shear stress (τ), the maximum normal stress is given by which of the following expressions?
- 1(σ/2) + (1/2)√(σ2 - 4τ)
- 2(σ/2) + √(σ2 - 4τ2)
- 3(σ/2) + (1/2)√(σ2 + 4τ2)✓
- 4(σ/2) - (1/2)√(σ2 + 4τ2)
Correct answer
(σ/2) + (1/2)√(σ2 + 4τ2)
