WHY
Does this happen with every calculation?
Looking for formulas and tables
Each calculation means looking up formulas, factors and tables in books and catalogues.
Mixed-up units
kgf and N, mm and m: converting units is where mistakes creep in.
No record of the basis
A value worked out on a calculator or spreadsheet loses its formula and assumptions later.
Where the values go
You would rather not send design values to an outside service.
FEATURES
What it does
Formulas and working

A verdict
Shows whether the conditions are met, within the conditions you entered.
Study sheets
Chain calculations and compare the current design with options A and B.
Design calculation sheet
