1. To be acquainted with the essential concepts of KINEMATICS that is related with the motion of RIGID BODIES. To determine its velocity and acceleration. 2. To know how to determine velocity fields and contemporaneous accelerations in absolute or relative motions of the various mechanism components in an arbitrary 3D motion. 3. To identify what happens on a solid due to its motion (mass and inertia). 4. To know how to determine the dynamic balance of mechanical systems through vector theorems, energy theorems, impulse theorem and quantity of movement. 5- LEARNING OUTCOMES By the end of the semester, students should know how to analyze the kinematic and dynamic behaviours of plannar and spacial mechanisms. Understand the kinematics and dynamics of trivial mechanisms (gears, rolling bearings, cam - follower, piston ring-cylinder liner, rolling/sliding contacts ...)

Previous knowledge of Physics and Mathematics from the secondary school.
From the first year the concepts provided by the disciplines of Algebra and the fundaments os statics of Mechanics I are very important.
Kinematics of a point. Trajectory Position vectors, velocity vectors and acceleration vectors. Vector’s components in intrinsic coordinates and in various Cartesian coordinates (steady or movable) Vector treatment of rotation motion “Angular velocity” vector or “rotation” vector “Angular acceleration” vector Kinematics of a solid Velocity fields Connection between velocities and two points of a solid: 1st Mozzi equation Elementary motions of a solid: translational and rotational Some particular motions: plain motion, polar motion and helical motion “General” motion: from “tangent” motion to helical motion. Absolute velocity, relative velocity and transport velocity Absolute acceleration, relative acceleration, transport acceleration and complementary (Coriolis) acceleration Solid motion on permanent contact Slip acceleration Velocity fields on constant contact Particular cases: pure rolling, pure twist, pure slip Rotation motion from the place where two motion solids meet and constant contact solids Instantaneous axis of rotation in an arbitrary motion of a solid Rotation motion of that axis Axoid surfaces Mass Kinematics Torsor motion Torsor acceleration Kinematic energy in a material system Dynamics- Force, Mass and Acceleration Dynamics of a material point The elementary principles of dynamics Equations of motion Inertial force Kinematic momentum variation of a material point Equation of dynamics Dynamics of a solid: Method of analysis, motion of the center of mass, motion around the center of mass, dynamic balance, particular motions and applications.

According to General Evaluation Rules of FEUP
1. Students will have to attend to two exams (November 2015; January 2016) 2. The first exam will exclusively test the concepts of kinematics. 3. The second exam will test the themes taught on the second part of the semester. 4. Both exams worth 45% of the final grade. 5. Students will have to achieve a minimum grade of 8 (7.50) out of 20 on each of the exams. 6. Realization of 4 homeworks using Moodle platform with a worth of 10% of the final grade.
Students who:
-did not reach an average grade of 10 out of 20 in referred evaluation,
- reached an average grade of 10 out of 20 but did not follow the rule on item 5,
- missed one of the exams,
will have an opportunity to be tested in February 2016 (worth of 90%). The exam will be cover what have been taught during the semester. All the students can have acces to this final exam, including the ones that have already have been approved and are interested to improve their classification.
