Mechanics - Statics and Dynamics

Valid for: 2013/14

Decided by: Education Board E

Date of Decision: 2013-04-17

Main field: Technology.

Compulsory for: Pi1

Language of instruction: The course will be given in Swedish

- give knowledge about the basic concepts in mechanics for material systems at rest and motion
- give knowledge and skills in engineering modeling

Knowledge and understanding

For a passing grade the student must

- be able to explain and apply fundamental concepts as force and moment, linear and angular momentum, linear and angular impulse and express them both as scalars and vectors
- be able to draw a free body diagram of a material body and set up the equations of equilibrium and motion
- be able to use the balance equations for a particles and rigid bodies in plane motion
- be able to describe velocities and accelerations in Cartesian, polar and natural coordinates systems

Competences and skills

For a passing grade the student must

- starting with a real situation be able to delimit a problem and treat material bodies such as particles and rigid bodies
- be able to apply systematically methods to mechanical systems in equilibrium and particles in motion
- be able to present written solutions to mechanical problems with suitable drawing and free body diagrams
- develop ability to solve problems by applying mathematical methods within linear algebra and the theori of ordinary differential equations

Judgement and approach

For a passing grade the student must

- evaluate the physical consistence of the obtained results
