Figure 1).
Use the prepared free body diagram to find the equation of motion for the submarine.
Prepare diagrams of the model under various conditions in Simulink and run each simulation
for 30 seconds.
Use the given damping coefficient values to determine the stiffness values.
Run each simulation using the stiffness values calculated in step 4. Determine the maximum
velocity of the submarine and the maximum force and elongation in the towing cable for the
system using each calculated stiffness value.
Plot all results, then compare the velocity, towing force, and elongation for each set of
conditions.
