Charpy test

The Charpy test measures the toughness of a material, like metal, by seeing how much energy it absorbs when struck with a swinging hammer. A standard sample is held in a machine, and a pendulum is released to hit the sample's notched side. The test determines how much force the material can withstand before breaking, helping engineers understand its durability and suitability for different uses. It's commonly used in industries like construction and manufacturing to ensure materials will perform safely under stress.
