Questions and Answers

What is the significance of point D in the stress-strain diagram?

Point D represents the ultimate tensile stress point, where the ultimate stress is calculated.

What is the primary characteristic of brittle materials?

Brittle materials show very small elongation before they fracture.

What is the definition of strength in the context of mechanical properties?

Strength is the resistance offered by a material when subjected to external loading.

What is the distinction between ultimate stress and breaking stress?

Ultimate stress is calculated at point D, while breaking stress is the stress at point E, where fracture occurs. Signup and view all the answers
