... With this adjustment, the largest three-month range occurs in February-April and is 71 њF. The range for all year, still removing the January 1962 record low, is 88 њF. The expansion coefficient for aluminum alloy 6061 is 24.3 microns/m-њC while that for borosilicate glass E6 is 2.8 microns/m-њC. The expansion coefficient difference is 21.5 microns/m-њC. Combining this number with the scale factor equation from the previous section gives a coefficient of 0.207 mm/њC for primary motion. ...
