Shore durometer is in MPa. Another linear relation between the ASTM D2240 hardness value and material elastic modulus has the form where formula_14 is the ASTM D2240 type A hardness, formula_11 is the ASTM D2240 type D hardness, and formula_2 is the Young's modulus in MPa. Shore durometer The Shore durometer is a device for measuring the hardness of a material, typically of polymers, elastomers, and rubbers.. Higher numbers on the scale indicate a greater resistance to indentation and thus harder materials. Lower numbers indicate less resistance and softer materials. The term is also used to describe a material‘s rating on the
Chicago North Shore and Milwaukee Railroad 1979. The outbreak of World War II caused the railroads of the United States to see a sharp rise in traffic. Even before the imposition of rationing of fuel and rubber made auto travel difficult, the North Shore saw its freight and passenger traffic rise to record levels, in part due to the railroad serving important military facilities: the Army's Fort Sheridan just north of Highwood, and the Navy's Great Lakes Naval Training Station, just south of North Chicago. North Shore saw its traffic increase to the extent that the railroad was forced to borrow equipment from the Chicago Rapid
