This paper is an extension to a Part 1 analysis of the deflection for a telescopic cantilever beam [1]. The Tip Reaction Model, proposed in that paper, establishes reactions at the tips of the overlapping portions as the mechanism of transfer of the external loads between sections of the telescopic beam. In Part 1 a three-section telescopic beam was analysed for deflection using these forces within a repeated integration method. In Part 2 the bending and shear stresses for the three-section cantilever, are obtained both analytically and numerically. A check upon stress levels is provided from a parallel study upon an equivalent, two-stepped, continuous beam. Graphical presentations of the beam stresses, found from applying the two methods to each structure, are self-validating. That is, the continuous beam theory provides a check upon numerical stress levels from FEA and, in turn, FEA provides a check upon the analytical stresses calculated from tip reactions within a telescopic beam. The fact that comparable stress levels were found confirms that the analytical technique proposed is perfectly adequate for a telescoping beam, just as the classical theory is adequate for continuous beams. Taken together, Parts 1 and 2 provide an analytical theory for bending of a discontinuous beam that did not exist heretofore, thereby obviating the need for a numerical solution.
