- Tensile test is a method to investigate the elasticity of a material. A test specimen is placed between two clamps and these clamps will move in opposite directions, hence straining the test specimen. This experiment will yield a stress-strain curve that shows each of the stages of the specimen for every load is applied. With an aid of sketching diagrams, describe the stages that the specimen experiences before it breaks, and relate it with the stress-strain curve. It is expected that each stage comes with a sketching of the specimen and explanation of the current stage.arrow_forwardConsider an aluminum specimen with a diameter of 10 mm and a length of 1 point 3 m.
