Chapter 6, Problem 1CQ

To determine

The result obtained by dividing the tensile force with the original cross-sectional area of specimen.

Answer to Problem 1CQ

The result obtained by dividing the tensile force with the original cross-sectional area of specimen is Engineering Normal stress.

Explanation of Solution

Consider a specimen having a cross-sectional area as $A$ and a tensile force with magnitude $F$ acts axially on it. As the applied force tries to deform the material the material experience the restoring force over the cross-section.

The result of this tensile force over the cross-sectional area over the specimen is known as engineering normal stress.

Thus, the result obtained by dividing the tensile force with the original cross-sectional area of specimen is Engineering Normal stress.
