Applied Physics

Vectorial and differential calculus; basic notions of mechanics (movement, force, energy)

In theorethical lessons the subject is presented. In theorethical-practical lessons problems of real life interest are solved. In the laboratory lessons experimental work is peformed by the students with the submission of a report until the end of the lesson. 

Concepts in kinematics, dynamics, energy and power of the rigid body are presented, illustrated by real life examples. The final objectives are to be able to understand and conceive gears and machines involving rigid Bodies, including: a) knowledge of the laws of Physics that apply to the motion of rigid bodies; b) ability to understand gears nvolving rigid bodies. c) ability to apply this knowledge to real life problems.

1. Kinematics of rigid bodies

Definition of rigid body and limits to the practical application of the concept

Angular velocity and angular acceleration of a rigid body

Velocity distribution over the rigid body

Acceleration distribution over the rigid body

Translation motion

Rotation motion

General motion

Relative vectors: position, velocity and aceleration

Centre of rotation and and instantaneous centre of rotation

Analysis of mechanical gears with fixed, sliding and non-sliding joints

2. Dynamics of the rigid body

Momentum of a force

Torque

Translation motion

Physical quantities in rotation

Rotation centered in the centre of mass

Rotation of eccentric gears

General motion

3. Work and energy of the rigid body

Kinetic energy of the rigid body

Definition of work

Work of a force

Work of binary

Work of conservative forces

Power associated with a force or with a binary

Kinetic energy theorem for gears

The laboratory lessons imply 4 practical works from which a minimum of three reports are mandatory for approval. Each practical report will be marked from 0 to 1. A total score of under 2.0 will prevent the student from getting approval on the subject. Final grade will be the sum of the reports marks (total maximum score 4) and the final exam, scored to 16.

Students with working student status are exempt from performing practical works and are evaluated exclusively by final exam, scored to 20.
