Question
Is stress a vector quantity?
✓

Answer

$\text{stress}=\frac{\text{Mognitude of restoring force by solid}}{\text{Area of cross - section}}$

as deforming and restoring force are equal and opposite so no net direction is involved.

Hence, the stress is not a vector quantity just like pressure.
