Simply supported beam evaluations

SS_Beam.m computes simply-supported or Pinned-pinned beam mode shapes & natural frequencies

% HELP: This script computes mode shapes and corresponding natural

% frequencies of the simply-supported beam by user specified mechanical

% properties and size of the beam.

% Prepare the followings:

% - Material properties of the beam, viz. density (Ro), Young's modulus (E)

% - Specify a cross section of the beam, viz. square,rectangular, circular

% - Geometry parameters of the beam, viz. Length, width, thickness

% - How many natural frequencies and mode shapes to evaluate.
