WebbThe Bernoulli-Euler beam theory (Euler pronounced 'oiler') is a model of how beams behave under axial forces and bending. It was developed around 1750 and is still the method that we most often use to analyse the behaviour of bending elements. This model is the basis for all of the analyses that will be covered in this book. WebbAs it turns out, you can calculate it - but the resulting equation, on first sight, is not all that simple. Calculus gives us 1 r ( x) = z '' (1 + z ' 2) 3/2 with z ' and z '' denoting, as usual, the first and second derivatives of the function z (x) Mercifully, it's not as bad as it looks.
