In a twodimensional stress analysis, the state of stress at a point $P$ is $\begin{bmatrix} \sigma \end{bmatrix} = \begin{bmatrix}\sigma_{xx} &\tau_{xy} \\ \tau_{xy} &\sigma_{yy} \end{bmatrix}$ The necessary and sufficient condition for existence of the state of pure shear at ... $\tau_{xy}=0$ $\sigma_{xx}+\sigma_{yy}=0$ $(\sigma_{xx}\sigma_{yy})^2+4\tau^2_{xy}=0$

In a twodimensional steady flow field, in a certain region of the $xy$ plane, the velocity component in the $x$direction is given by $v_x=x^2$ and the density varies as $\rho = \dfrac{1}{x}$. Which of the following is a valid expression for the velocity component in the $y$ – direction, $v_y$? $v_y= \:– x/y$ $v_y = x/y$ $v_y = \:xy$ $v_y = xy$
