Stress is tensor,then,what is meant by tensor? (Rupasri asked)

Tensor is a mathematical object analogous to but more general than a vector, represented by an array of components that are functions of the coordinates of a space.

Tensors are used to represent correspondences between sets of geometrical vectors.

Physically, vectors are used to represent locations, velocities, accelerations, flux densities, field
quantities, etc.
