Question

Stress is scalar or vector?and how?​

Answer 1

Answer:

Yes, force is a vector, and surface can be seen as a vector as well, but when you say "stress", it means "magnitude (scalar) of the force perpendicular to that element of area. ... It is a scalar because it is "total force" (magnitude) over a surface whose orientation has already been described.

Answer 2

Answer:

scalar if there is only given scalar or vector

the answer is tensor

Explanation:

According to terms in Physics,

Scalar is a quantity having only magnitude.

A vector is a quantity that has magnitude and direction both.

Tensor is a quantity having magnitude, direction, and plane too.

Stress is a tensor as it obeys the coordinate transformation law. Stresses are not vectors because they do not combine according to the parallelogram law of addition. Instead, stresses are much more complex quantities than the vectors and are called tensors. Stress is a second-order tensor. Also, it has a dimension too.
