#### Course aims:

To study the movement of material systems taking into account the causes of motion (dynamics and analytical mechanics) and not taking into account the causes of motion (kinematics)
Accumulation of knowledge from Mechanics (Cinematics, Dynamics, Analytical Mechanics) regarding the movement of material systems. The possible movements as well as those caused by forces are studied. Knowledge regarding the movement of the material point in space and plane.
Acquire knowledge about CSR (solid rigid body) motion in space and plane, as well as body systems. Travel charts. Differential equations of material point motion and CSR in its different movements. Principles of Analytical Mechanics.
- It is known to determine the trajectory, speed and acceleration of a moving point, under certain conditions. - To calculate the speed and acceleration of the bodies in different types of movements - Knowing how to draw the displacement diagrams for a 1GLC plane mechanism (kinetic freedom degree)
To know how to calculate the kinetic quantities (kinetic energy, mechanical work, momentum, kinetic moment) of a material point in motion, respectively of a body and system of bodies.

#### Teaching methods:

Lecture, discussions, examples

#### Learning outcomes:

Mechanics being a fundamental discipline, the content of the discipline is necessary for the study of other disciplines, such as the resistance of the materials, the static of the constructions, disciplines that form the basis of the specialized disciplines necessary for the graduates in the field of design and execution.

#### Learning outcomes verification and assessment criteria:
