(HP-65) Beam Vibration frequencies (schelkunoff iteration)

[SlideRule]

An extract from Frequencies of vibration of beams by Schelkunoff iteration, Computers & Structures Vol 7., pp.639-650. Pergamon Press 1977

Abstract - Three programs are given for computing frequencies of free vibrations of uniform beams with the HP-65 programmable, pocket calculator: Bernoulli beams with all 10 combinations of homogeneous end-conditions, two-span Bernoulli beams on hinged supports and Timoshenko beams with 9 of the 10 combinations of homogeneous end-conditions. The programs illustrate the capacity and versatility of the calculator and various strengths and weaknesses of Schelkunoff's iterative method for solving trigonometric equations.
