A Charpy V-notch specimen is tested by the impact-testing machine. In the test, the 15 kg hammer of arm-length 120 cm (measured from the fulcrum to the point of impact) is raised to 90° and then released. i. What is the potential energy stored in the mass (hammer) when it hit the specimen, in J? i. After fracture of the specimen, the hammer swings up to 45°. What is the potential energy at this point, in J? i. How much energy lost during impact (toughness of specimen), in J?
