SUMMARY

The discussion centers on a homework problem involving movement in a non-inertial reference frame, specifically addressing roll, sway, and heave movements. The participant attempted to analyze the system as a harmonic oscillator but faced challenges in interpreting the diagram provided, particularly regarding the fixed pole and the mass supported by a cable. The complexity of the system is highlighted by the presence of at least four degrees of freedom (DOF), indicating a need for a thorough understanding of dynamics and kinematics in non-inertial frames.

PREREQUISITES
  • Understanding of non-inertial reference frames
  • Familiarity with harmonic motion and oscillatory systems
  • Knowledge of degrees of freedom (DOF) in mechanical systems
  • Basic principles of dynamics and kinematics
NEXT STEPS
  • Research the principles of dynamics in non-inertial reference frames
  • Study harmonic oscillators and their applications in mechanical systems
  • Explore the concept of degrees of freedom (DOF) in multi-body systems
  • Examine the effects of external forces on oscillatory motion
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and dynamics, as well as engineers and researchers working with non-inertial systems and oscillatory motion analysis.

You have all the freedom to make any assumption to solve the problem. All 3 kinds of movement must be considered (roll, sway, heave). Variables are up to you.



Homework Equations




The Attempt at a Solution



I tried to solve it by considering it an harmonic system.

It is not clear what is depicted in the upper right part of the figure. Is that a fixed pole with the mass supported on a cable from the bottome of the pole? What is the solid, angled line from the top of the pole to the ship? What is the coordinate theta supposed to represent?

Whatever this system is, it looks like you have at least 4DOF involved, so it is going to be a bit messy.
