1. Particle pendulum with airresistance (2D dynamics)



The figure to the right shows a particle Q of mass m = 100 kg
at the distal end of a straight cable B of length L = 50 m.
Earth's local gravitational acceleration is g = 9.8 m/s^{2}.
Airresistance of force 2*v resists the pendulum motion.
This problem shows how to use MotionGenesis™ to determine
the pendulum angle q and cable tension as a function of time.


To simulate/plot with MATLAB®, edit ParticlePendulumFma.txt, and
change ODE() ParticlePendulumFma to ODE() ParticlePendulumFma.m

Alternately, use this MotionGenesis™ file to autogenerate a
MATLAB® .m file with plant dynamics (e.g., for Simulink^{®}).






2. Rigidbody pendulum (2D dynamics)



The figure to the right shows a nonuniform rigid rod A attached
by a frictionless pin joint to Earth N (a Newtonian reference frame).
The only external forces on rod A are contact forces at No
(the point of N in contact with A) and Earth's gravitational force.
