Structural Mass Element (MASS21) Input Listing: vm91.dat Test Case
A pendulum consists of a mass m supported by a rod of length and cross-sectional area A. Determine the
motion of the pendulum in terms of the displacement of the mass from its initial position Θo in the x and y directions, δx and δy, respectively. The pendulum starts with zero initial velocity.

A large deflection solution is required. An initial time step is defined over a small time increment (.01/5 = .002
sec) to allow an initial step change in acceleration to be attained. Subs...
