Is Stress a Scalar or Vector or Tensor Quantity? Is it same for Pressure also?

stress is a scalar quantity;; it is force per unit area and same is for pressure
Marjaan Mahmood
I had the doubt because when I think a condition like this. When two forces of different magnitude acts oppositely on a block which is at rest, in a manner that the force per area on one side is equal to the force per area on other side. The net force is zero?? Or If yes.Force/Area is a vectore as the negative signs results their sum in to 0.

Stress is actuallyneither scaler nor vector quantity, it is a tensor. However it can reffered as Cuchy Traction Vectot T.

newton’s second law is defined for net unbalanced force not unbalanced stress.Stress is used to define static behaviour.Thesituation u are assuming ,there is unabalance so your system can’t be at rest.stress is defined for a point.

stress seems to be scalar same as that of pressure but when force is involved in a specified direction in stress it is a vector;hence it is neither a vector or scalar so.
