Question

Define Tensor quantity ........also give one example....

Answer 1

scalar and a vector are both tensors! Scalar = tensor of rank 0, vector = tensor of rank 1, dyadic = tensor of rank 2, etc. A tensor is a general quantity. A scalar has magnitude with 0 direction, hence a rank 0 tensor. A vector is a magnitude acting along a line, or 1 dimension, i.e. tensor of rank 1.
