Q.69 & The state of strain at a point in a machine component is given as \\
$\varepsilon_{x x}=2.5 \times 10^{-4}, \varepsilon_{y y}=2.0 \times 10^{-4}, \varepsilon_{z z}=-1.5 \times 10^{-4}, \varepsilon_{x y}=2.5 \times 10^{-4}$, \\
$\varepsilon_{y z}=-0.5 \times 10^{-4}, \varepsilon_{z x}=-1.0 \times 10^{-4}$. The volumetric strain at this point is \\

• A. & $4 \times 10^{-4}$ \\
  \hline
• B. & $3 \times 10^{-4}$ \\
  
• C. & $-5 \times 10^{-4}$ \\
  
• D. & $-3 \times 10^{-4}$
