EXPERIMENTAL CAPABILITIES
1. Single-rotor system.
a) frequency of oscillation
b) Polar moment of inertia (J) of flywheel by oscillation

2. Damped single-rotor system (step response).
a) light damping - logarithmic decrement
b) heavier damping - first overshoot
3. Damped single-rotor system (harmonic response).
a) amplitude ratio against frequency ratio
b) phase lag against frequency ratio
c) polar response diagram
4 Simple two-rotor systems.
