Question

In a tension test, fracture takes place along a crystallographic plane, on which the normal tensile stress is maximum. Such plane is called

• A. Shear plane
• B. Neutral plane
• C. Cleavage plane
• D. Fracture plane

Answer 1

Answer:

C. Cleavage plane

During a tension test, the fracture occurs on a crystallographic plane known as the cleavage plane, where the normal tensile stress is at its maximum. This test provides information on various mechanical properties of materials such as strength, ductility, and toughness. The results obtained from the test include proportional limit, elastic limit, modulus of elasticity, yield strength, ultimate tension strength, modulus of resilience, modulus of toughness, percentage elongation, and percentage reduction in area.
