Question

Stress distributed over an area is best described as: a) External force b) Axial force c) Radial force d) Internal resistive force none of these e

Answer 1

Answer:

Option D is the correct answer.

Explanation:

Stress is the force per unit area that tend to change the shape of body.

Stress is defined as internal resistive force per unit area.

         $\texttt{Stress}=\frac{\texttt{Internal resistive force}}{\texttt{Area}}$

         $\sigma =\frac{F}{A}$

So, so stress distributed over an area is best described as internal resistive force.

Option D is the correct answer.
