Shore durometer °Sh or >90 °Sh the results are not to be trusted. The measurement must be redone with adjacent scale type. Durometer is a dimensionless quantity, and there is no simple relationship between a material's durometer in one scale, and its durometer in any other scale, or by any other hardness test. Using linear elastic indentation hardness, a relation between the ASTM D2240 hardness and the Young's modulus for elastomers has been derived by Gent and by Mix and Alan Jeffrey Giacomin. Gent's relation has the form where formula_2 is the Young's modulus in MPa and formula_3 is the ASTM D2240
Chicago North Shore and Milwaukee Railroad Chicago North Shore and Milwaukee Railroad The Chicago North Shore and Milwaukee Railroad, also known as the North Shore Line, was an interurban that operated between the Chicago Loop and downtown Milwaukee. The 85-mile route of the North Shore Line utilized a combination of private rights-of-way and street running as well as trackage rights over the Chicago "L" network. In addition to operating passenger and freight trains, the company also provided streetcar and motor bus services throughout its history. Originating in 1895 as an electric street railway in the city of Waukegan, the property was gradually transformed into what author
