Se realiza un ensayo de impacto Charpy sobre una probeta de sección cuadrada de 10 mm de lado. La probeta tiene una entalladura en U de 5 mm de profundidad. El péndulo tiene una masa de 30 kg y se suelta desde una altura de 1 m. Tras el ensayo el valor de la resiliencia obtenida es de 254 J/cm2. A) Determine la energía total absorbida por la probeta en la rotura b) Calcule la altura que adquiere el mazo después de la rotura
