Course Aim
The content of the course is a continuation of the basic courses in mechanics and aims for students to further broaden and deepen their knowledge of classical mechanics, which also becomes a base for further studies in physics and space engineering such as for orbit and attitude dynamics. It also includes alternative methods within classical mechanics.

After passing this course the student can:

1.    Knowledge and understanding
  • describe and express  the conditions for body equilibrium in three dimensions.
  • account for concepts and explain basic concepts and laws within three-dimensional classical particle and rigid dynamics with significance for space engineering.
  • explain inertial forces and describe when they occur.
  • account for systems undergoing damped and forced vibrations, explain resonance and exemplify  its consequences such as for space rockets.
  • describe basic principles for propulsion of aircrafts and space rockets.
  • describe analytical mechanics as an alternative method to Newton's laws, can elucidate basic concepts and account for Lagrange's equations.
2.    Competence and skills
  • determine the conditions for force equilibrium of bodies in three dimensions.
  • solve problems with movement of bodies in three dimensions i.e. make calculations based on translating, accelerating and rotating coordinate systems, use Newton's laws, energy methods, momentum, inertial matrix, Euler's equations for gyroscopic motion and analyze damped, forced and coupled oscillations.
  • calculate dynamic forces in rotating mechanical systems due to dynamic imbalance.
  • solve problems with central-force motion, especially planet and satellite orbits.
  • solve dynamic problems for particles and rigid bodies using analytical mechanics:
            a)    formulate Lagrange function for different physical situations;     
            b)    derive the equations of motion and solve Euler-Lagrange's equations for mechanical systems with one or a few generalized
  • calculate mass flow and acceleration when propelling a rocket.
  • make a mechanical design to fulfill more complicated technical dynamics problems (vibration problems) by using simulations.
  • communicate model and simulation in a structured scientific report.

3. Judgement and approach
  • use a scientific approach to critically evaluate results, draw conclusions and argue for a chosen technical solution for space technology.

Vibrations: free, damped and forced vibrations in mechanical systems; satellites and vibrations.

Kinematics and kinetics of particle systems in applications with examples in rocket propulsion.

Analytical mechanics: force constraint; degrees of freedom; generalized coordinates; generalized momentum; invariances and conservation laws; the Lagrange function and Euler-Lagranges equations.

Dynamic modeling and mechanical design with computer aids (normally Comsol Multiphysics, alternatively Matlab).

Each course occasion´s language and form is stated and appear on the course page on Luleå University of Technology's website.
The teaching consists of lectures and lessons. In order for the student to achieve the course objectives, the student is encouraged to participate in these learning activities, read the corresponding sections in the course literature and solve the proposed exercises. It is mandatory laboratory work on gyroscopic motion and hand-in assignments/computer assignments.

The assignment involves identifying a more technically advanced dynamic problem related to space engineering by using computer-based aids for mechanical design, visualization and simulation. Normally, this is analysis, development and optimization of a CubSat frame to fulfil given vibration criteria during launch.

If there is a decision on special educational support, in accordance with the Guideline Student's rights and obligations at Luleå University of Technology, an adapted or alternative form of examination can be provided.

It is normally a written examination with differentiated numerical grades at the end of the course. In addition, approved report of hand-in assignments and presentation of laboratory results, are required.


The course can not be a part of the degree together with F0008T Mechanics II.
