... only the 30 to 60 mm of the block near the surfaces. For blocks under 10 0 mm this is the entire block, and there is no problem. For longer blocks, there is a variable amount of the block in the ... expansion coefficient of 11 .5 x 10 -6 /ºC. This means that a 10 0 mm gauge block will grow 11 .5 x 10 -6 times 10 0 mm, or 1. 15 micrometer, when its temperatu...
