Learning outcomes
Knowledge and understanding
For a passing grade the student must
- be able to define and apply fundamental concepts such as
force and moment of force, linear and angula momentum, impulse and
moment of impulse, and be able to express them both in scalar and
vectorform
- be able to draw a free body diagram of a material body and
to set up the equations of equilibrium and motion
- be ably to describe velocities and accelerations in Cartesian,
polar and natural coordinates systems and use the the force and
moment equationsfor a particle
- be able to use the velocity and acceleration fields in rigid
body motionl
- be able to define and use the basic concepts linear
momentum, angular momentum, impulse and moment of impulse, moment
of inertia, power, energy and work for a rigid body
- be able to use the force and moment equations to describe plane
rigid body motion
- be able to analyze practical problems in mechanics
- be able to use MATLAB in the solution of problems in
mechanics
Competences and skills
For a passing grade the student must
- starting with a real situation be able to delimit a problem and
perform an equilibrium analysis
- be able to apply systematic methods in an analysis of
mechanical systems in equilibrium and particles in motion
- starting with a real situation be able to delimit a problem and
treat material bodies as particles or rigid bodies
- be able to apply systematical methods to mechanical systems in
motion
- be able to present written solutions to mechanical problems
with suitable drawing and free body diagrams
- given a project specification be able to delimit a problem and
create a model which may be analyzed using in a simulation
sofware.
Judgement and approach
For a passing grade the student must
- evaluate the physical consistency of the obtained results
