ENSAIO DE COMPRESSÃO
ENSAIO DE COMPRESSÃO
AVALIAÇÃO DOS RESULTADOS
1. Crie uma tabela semelhante à apresentada abaixo para cada um dos materiais. Anote os valores da carga e alongamento sofrido pelo corpo, para intervalos de 5 kgf/cm². Note que a carga é dada pelo manômetro em kgf/cm² e a unidade requerida para a análise dos dados é MPa. Converta os valores obtidos no experimento utilizando a relação abaixo.
1kgf/cm² = 0.098067 Mpa
