Aim

• give knowledge about the basic concepts in mechanics for material systems in motion

• give knowledge and skills in engineering modeling

• develop ability to solve problems

Knowledge and understanding
For a passing grade the student must

• be able to explain and apply fundamental concepts as linear and angular momentum, linear and angular impulse, moment of inertia, energy and work for a rigid body.

• be able to use the balance equations for particles and rigid bodies in plane motion

• be able to describe velocities and accelerations in Cartesian, polar and natural coordinate systems

Skills and abilities
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 systematical methods to mechanical systems in motion

• be able to present written solutions to dynamical problems with suitable drawing of free body diagrams

• be able to delimit a problem from a given project specification and create a simulation model for solving the problem

Judgement and approach
For a passing grade the student must

• evaluate the physical consistency of the obtained results
