'Maths Day' event.

The topic of 'mathematics
in the field of structural me-
chanics' was a source of
lively interest. During his
30-minute talk, Johannes
Blödt from SIMENT GmbH
dealt with the mathematics
used in SCHERDEL's
SpringDesigner software. The SpringDesigner software for compression springs is the ideal tool for application engineers.
Using the program as a tool
for theory building, he was grams that apply a linear force to calcu- pects. For instance, carrying out colli-
