Question

The linear strain in x ,y and z directions are $e_x,e_y$ and $e_z$. respectively. Then the volumetric strain is given by

• A. $e_xe_ye_z$
• B. $e_x+e_y+e_z$
• C. $e_z=e\,e$
• D. $e_z=\frac{e_x+e_y}{2}$

Answer 1

Answer: (B)

$e_x+e_y+e_z$

Answer 2

Given Linear strains in $x, y \& z$ dir $^{N}$ are $\epsilon_{x}, \epsilon_{y} \& \epsilon_{z} .$ To find $\rightarrow$ volumetric strain $=?$ soln we knaw that $\begin{array}{l} \epsilon_{v}=\text { volumetric strain } \\\ \epsilon_{v}=\epsilon_{x}+\epsilon_{y}+\epsilon_{z} \end{array}$
