 **Allowable Free Length or  Degrees for a given tolerance (summary display).**

Note: Calculations may not be correct when using wire diameter 
over .500 due to the decreasing modulus and the manufacturing 
technique used for large wire types.

Spring-Pro calculates 80 percent of the total Free Length and Degree Tolerance from the  actual
tolerance available from the Tolerance load value entered.  This is due to the fact that in the
manufacturing of springs other variations such as Outside Diameter, Active Coils, Material tensile strength etc will decrease the actual tolerance available.

Values for natural period of vibration (n') per second for an unloaded steel springs has been added to
the compression spring summary display.
