How is compressive stress calculated in relation to the applied force and the test specimen?

Show Answers

Surface area of the specimen where the load is appliedThe specimen's elasticity measured through strainThe specimen's length under the applied loadStrain experienced by the specimen per unit length

Explanation

Compressive stress is determined by dividing the external force by the area of the specimen that bears the load. This area is crucial because stress is defined as force per unit area. Other options describe properties like elasticity or strain, which are not used to calculate stress directly.
