### Spring Diagram

Spring diagram is displayed in wizard page:

The equation of spring line **M = R**_{MR} * α or **M = R**_{MRv} * n_{rev} is determined.
Get with this equation the torsional moment **M** for a given angle **α** or number of revolutions **n**_{rev}.
With the inverse equation **α = M/R**_{MR} or **n**_{rev} = M/R_{MRv} the angle **α** or
number of revolutions **n**_{rev} is determined to obtain a given torsional moment **M**.
The maximum permissible torsion angle **α**_{n} or torsional revolutions **n**_{revn} and
maximum permissible torsional moment **M**_{n} are calculated.

## Verification Calculation of a Torsion Spring

The verification calculation can only be done if the dimensions of the spring and the load are known. The calculation is done according
the standard **DIN EN 13906-3**. The safety factors for static and dynamic failure are calcualted. The same calculation steps
as in the design operation are performed, except those for calculation of the dimensions. The **natural frequency** in
transverse direction is calculated.
