016 (UMC-SP) Um aluno do curso de engenharia mecânica da UMC deseja medir a temperatura de um forno utilizando uma barra metálica de comprimento igual a 1 m, que se encontra inicialmente a 22 °C. A barra é introduzida no forno e, ao ser retirada, o aluno verifica que o seu comprimento passa a ser 1.01 m. Sabendo que a variação de comprimento (/L) é diretamente proporcional à variação de temperatura (/t) e ao comprimento inicial (L0), pede-se determinar a temperatura do forno, Dado: Coeficiente de dilatação linear do metal 10. 10-6
