54. Stress can be defined as ________ quantity. A.Scalar B.Vector C.Phasor D.Tensor
Option D Solution: Stress is defined as resisting force per unit area of an element, on which load is applied. Stress is always perpendicular to a cross-section in the element. It is neither scalar (it cannot be numerically added), nor is it a vector (it does not follow the triangle rule of vector addition). It is a tensor quantity because it describes things happening in two directions simultaneously.
