Rigid-Body Rotational Dynamics (Tank Spin System):

Tank Specs:

• Material → 304L Stainless Steel
  Length → 15 cm
  Radius → 4 cm
  Thickness → 0.5 cm
  Mass → 1.143 kg

Configuration:

• Thin-walled cylindrical tank approximation
  Instrumented with internal thermocouples
  Sealed end-cap with wiring feedthrough

Moment of Inertia (Izz):

• Izz = mR²
  Izz = (1.143 kg)(0.04 m)²
  Izz = 0.001829 kg·m²

Drive Torque:

• τ = 0.840 N·m

Angular Acceleration:

• α ≈ 459.4 rad/s²

Spin Rate Requirement:

• 2–3 RPM
  ω ≈ 12.57 – 18.85 rad/s

Spin-Up Time:

• t = ω / α
  t ≈ 27 – 41 ms

Power Estimate:

• P ≈ 6.5 W

Motor / Servo Notes:

• Torque–speed curve limits max RPM
  Servo must provide ≥ 0.84 N·m stall torque
  Continuous power ≥ 6.5 W

Design Task:

• Evaluate 4 candidate servos from electrical spreadsheet →
  Compare torque, speed, power, and mass to select optimal model.

FDIR = Continuously:

1. Observe system state

2. Compare to model/expectations

3. Flag anomalies

4. Enter a safe mode

5. Attempt recovery

6. Only return to nominal when consistent
