Detailed Description

Class for calculating the analytical solution to the Euler-Bernoulli beam model in fixed-free configuration.

Implementation of the classical analytical solution to the Euler-Bernoulli beam model in fixed-free configuration, for a cuboid beam, i.e.

\[ \eta(x) = \frac{q x^2 (6 L^2 - 4 L x + x^2)}{24 E J} \]

where \( q = g \rho(x) A(x) \), where \( g \) is the gravitational acceleration, \( \rho *\) the mass density and \( A(x) = H * K \) the area for the cross section,

where \( L \) is the length of the object, \( E \) is Young's modulus of elasticity and

where \( J = \frac{K H^3}{12} \) is the second moment of area for the cuboid with the neutral line in the centroid.
