The SES template has been created to simplify the process of proving structural equivalency.
As downloaded the spreadsheet assumes a baseline steel chassis design. The majority of the cells in the spreadsheet are locked, you can only edit the cells shaded yellow.
Cells shaded grey are dependant on the data entered in yellow cells, the formulae in these grey cells have been left visible so you can see how the results are calculated.
The vast majority of the tabs can be accessed using the hyperlinks on the cover sheet. If you enable macros when opening the document "Ctrl+e" will return you to the cover sheet.
There have been a few questions about how to handle bent/two piece tubes in place of a single baseline tube. If properly triangulated then the reinforced bent/two piece tube will be stiffer and stronger than the baseline tube, so please ensure you include images of the tube(s) in the "Chassis Pics" tab for the SES assessor to review. You may add additional proof of equivalence to the "Additional Info" tab if you deem it necessary. You do not need to adjust the number of tubes in the relevant calculation tab.
The SES has been extensively tested, but if you think you have found a mistake in the document or have any questions on how to use the template please submit a question to the FSAE rules committee in the usual manner.
