Unusual types of gramophone records did have etched labels as well, with many (if not all) also featuring a little etched picture of Thomas Edison. The Gramophone company etched their logo at the blank side of their single sided records in the early 1900s, in the same way, Some later single sided Red Seal records by Victor had a pattern with the word Victor on it. After having already released both colored vinyl singles and picture discs in the 1980s, Canadian rock artist Bryan Adams issued a 12" single of "Can't Stop This Thing We Started" in autumn 1991, which had the front cover photography
Polymer interest. These are the properties that dictate how the polymer actually behaves on a macroscopic scale. The tensile strength of a material quantifies how much elongating stress the material will endure before failure. This is very important in applications that rely upon a polymer's physical strength or durability. For example, a rubber band with a higher tensile strength will hold a greater weight before snapping. In general, tensile strength increases with polymer chain length and crosslinking of polymer chains. Young's modulus quantifies the elasticity of the polymer. It is defined, for small strains, as the ratio of rate of change
