Ship Vibration is dedicated to the ship engineering students. The application defines a symmetrical ship both as overall geometry and as the transverse structure. Using a modified Stodola iterative method, the application is able to calculate the first vertical and horizontal natural bending vibration mode. The ship definition can be saved in a text file into a folder from where it can be later loaded. The results are saved in graphic form.

SSB - Simple Supported Beam is dedicated to mechanical engineering students. It calculates the stresses and deformation of a beam made by up to 20 cylindrical spans and, also, calculates the 1st natural vibration mode shape and frequency, using a modified Rayleigh method.
