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
North Shore (Lake Superior) efforts, many of the forests along the North Shore are now protected from deforestation, but there is still a strong paper industry that relies on pulpwood. In 1855 when a lock system first allowed steamboats onto the lake, eastern tourists began to travel onto Lake Superior for recreational purposes. They would then canoe or be ferried from Duluth up the North Shore and would stay in hunting and fishing camps. In the 1920s, the North Shore highway was built, which helped make the North Shore accessible by land. At the same time commercial fishermen began to go out of business
