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
