Curved beams under transverse loads: notes
This form uses the classical theory of beams in simple bending as represented by the equation M=-EJy'' adapted for beams with circular axis.
The solution is based onto a polynomial-sinusoidal formula (exact) obtained from strain energy U minimization ('Options'->'Show formulae' in the menu to see, relationships enforcing boundary conditions not shown).
When present, the button 'Data' will download the vectors of coefficients (without dimensions) a,b,c,...,A,B,C,... as defined in sheet's formulae.
Note that it is up to the user to link the downloaded vectors to the input data: when you download it, the vectors correspond
to the data in the sheet as you view it.
