Compressive stress is computed by dividing the external force by the:
Correct Answer: Area of the test specimen upon which the weight rests
Description: COMPRESSIVE STRESS
When a body is placed under a load that tends to compress or shorten it, the internal resistance to such a load is called a compressive stress. A compressive stress is associated with a compressive strain. To calculate compressive stress, the applied force is divided by the cross-sectional area perpendicular to the axis of the applied force.
Key Concept: To calculate compressive stress, the applied force is divided by the cross-sectional area perpendicular to the axis of the applied force.
