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.

 


After passing this course the student should:

1.    Knowledge and understanding

• Have knowledge of the conditions for body equilibrium in three dimensions.

• Be able to define and formulate basic concepts and laws within three-dimensional classical particle and rigid dynamics which include relative motion in rotating, coordinate systems, central-force motion, Newton`s laws, angular momentum, momentum equations, energy methods, moment of inertia tensor, euler angles, Euler equations for gyroscopic motion, steady precession with zero moment and kinetic energy.

• Understand the concept of inertia forces and explain when they occur.

•  Be able to explain systems undergoing damped and forced vibrations and have knowledge about resonance and its consequences.

• Have knowledge of analytical mechanics as an alternative method to Newton's laws and be able to explain concepts such as constraints, degrees of freedom, phase-space, generalized coordinates, generalized momentum, the Lagrange and Hamilton functions.

 

2. Skills and abilities

 

• Be able to determine equilibrium conditions of bodies in the three dimensions.

• Be able to apply Newton´s laws and the momentum equation on three dimensional motion of bodies.

• Be able to perform calculations in rotating reference systems.

• Be able to calculate dynamic forces rotating mechanical systems and how these can be reduced with balancing.

• Solve problems with central motion.

• Have demonstrated the ability to use Newton's laws, energy methods, angular momentum, moment of inertia tensors and Euler's equations for gyroscopic motion in problem solving.

• Be able to analyze systems undergoing damped, forced and coupled vibrations.

• Be able to solve problems using analytical mechanics as an alternative method to Newton's laws, including Euler-Lagrange and Hamiltonian mechanics.

• Have demonstrated ability to formulate mathematical models and solve a mor technically challenging dynamic problems, both through idealized analytical solutions and by using computer-based tools (eg Matlab) for numerical solution.

• Show proficiency in oral and/or written presentations.

 

3.  Assessment and reasoning

• Practise problem solving.

• With a scientific approach, be able to evaluate whether results and calculations are reasonable and link the results to applications in engineering.

• Understand the limitations of analytical models and determine when numerical methods are to be used.

• Get awareness of different applications of mechanics in science and technology.

Alternatively, if agreed between student and examiner, the laboratory exercise can be to develop (including laboratory instructions) a student lab that can be used in physics teaching.


Examination

Written examination at the end of the course. Approved laboratory work and home/computer assignments are required There can be alternative examination methods.
