Objetivo general
Objetivo especifico
Cálculos
A través del presente laboratorio se pretende realizar los cálculos correspondientes para poder analizar, tener un buen aprendizaje y desarrollo del tema, guiados por la norma NTC 2289 y se presentaran a continuación:
- Porcentaje de alargamiento
Utilizando los datos de la tabla 3 que se encuentra en los anexos que presenta la longitud inicial y final de la varilla de acero podemos obtener el porcentaje de alargamiento que se presenta a continuación:
(1)
[pic 3]
Por medio de la fórmula 1 se obtiene el siguiente resultado:
[pic 4]
- Porcentaje de reducción de área
Análisis de resultados
En esta parte del informe se presentaran los diferentes análisis y descripciones de los cálculos presentados anteriormente.
Las barras una única resistencia a la fluencia mínima, conocida como 60 000 psi (420 MPa), designado como grado 60 (420). (ICONTEC, 2007).
Los resultados obtenidos anteriormente por medio de la ecuación 1 indican un porcentaje de alargamiento del 10,18% del cual se puede describir que la varilla de acero tuvo este alargamiento en porcentaje a medida que se le iba aplicando la fuerza de tracción y finalmente cumplió en su totalidad este alargamiento.
