The ability of a material to withstand a high velocity blow is known as?

• A. Impact strength
• B. Tensile strength
• C. Compressive strength
• D. Hardness

Answer: (A)

Impact strength is the ability of a material to resist fracture when struck by a sudden, high-velocity load. This property reflects how well the material can absorb energy during rapid loading, often measured with tests like Charpy or Izod where the energy absorbed before fracture indicates toughness. This is different from tensile strength (resistance to being pulled apart under gradual load), compressive strength (resistance to crushing under steady compression), or hardness (surface resistance to indentation). So for a high-velocity blow, impact strength best describes the material's behavior.
