Aim
The aim of the course is to:
- give knowledge about the basic concepts in mechanics for material systems at rest and motion, mainly for particles and rigid bodies
- give knowledge and skills in engineering modeling
- develop ability to solve problems by applying mathematics
Knowledge and understanding
For a passing grade the student must
- be able to explain and apply fundamental conception 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 give a detailed description of different application
- be ably to describe velocities and accelerations in Cartesian, polar and natural coordinates systems and use the balance equations for a particle expressed in vector format
Skills and abilities
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 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
Judgement and approach
For a passing grade the student must
- evaluate the physical consistence of the obtained results
