¿Cómo calculamos Rigidez compuesto? H

Estimación de la rigidez de un material consiste en el cálculo de su elasticidad.

Medir la longitud original del material compuesto antes de aplicar ninguna fuerza en él. Anote esta medida.

Aplicar una cantidad conocida de fuerza constante para el material compuesto. Anote esta cantidad.

Medir la longitud del material compuesto mientras está bajo la influencia de la fuerza constante que se aplica. Anote esta medida.

Determinar a través de la medición del área de la sección transversal del material compuesto a la que se aplica la fuerza. Registre el área.

Calcular el módulo de elasticidad, o la medida de la rigidez, del material compuesto utilizando esta fórmula: E = F (L1) / D (L2), donde F es igual a la fuerza aplicada, L1 es igual a la longitud original del material compuesto, A es el cruzar área de la sección, y L2 es la longitud del material compuesto con carga o fuerza.

Comparar el módulo de elasticidad calculado para el compuesto para el módulo de elasticidad de otras cantidades conocidas tales como acero, aluminio, vidrio, hormigón, madera y poliestireno para obtener una estimación comparativa de la rigidez o la elasticidad del material compuesto.
