engineering recuitment UPSSSC JE Civil 2024 Mock Test Strength of Materials Principal Stress or Strain Analytical Method of Analysis
When a body is subjected to direct tensile stress (p), in one plane accompanied by a simple shear stress (q), the maximum normal stress is
1
\(\frac{{{p}}}{2}\; + \;\frac{1}{2}\sqrt {p^2\; + \;4q^2}\)
2
\(\frac{{{p}}}{2}\; - \;\frac{1}{2}\sqrt {p^2\; + \;4q^2}\)
3
\(\frac{{{p}}}{2}\; + \;\frac{1}{2}\sqrt {p^2\; - \;4q^2}\)
4
\(\frac{{{p}}}{2}\; - \;\frac{1}{2}\sqrt {p^2\; - \;4q^2}\)
