Packet 7: Bonus 14

Specific term required. A 2025 MATLAB program created by Georgia Tech named for this process is a modern successor to a software developed by Franklin T. Dodge named “[this process]-XL.” For 10 points each:
[10h] Name this process that occurs in tandem with “slamming” to describe fluid motion in rigid tanks. This process can cause destabilization of a moving object as the center of mass of an internal fluid changes.
ANSWER: fluid sloshing
[10e] Sloshing can be reduced by baffles that induce this phenomenon. Tall buildings often install “tuned mass” counterweight devices named for this phenomenon.
ANSWER: damping [accept dampers or word forms]
[10m] Fluid sloshing is often modeled as a parametric oscillator that acts as a spherical one of these systems. Dynamic stabilization is illustrated by inverting one of these systems and connecting it to a PID controller.
ANSWER: pendulums [or pendula; accept inverted pendulums]
