MECHANICS 2

MECHANICS 2

ECTS Credits: 4

Objectives:

Engineering Mechanics mostly deals with the behaviour of bodies under the action of forces and moments. Dynamics is the branch of Mechanics which relates mechanical actions to motions and plays fundamental roles in Mechanical Engineering but also Bio-Mechanics and biology.

The general objectives of this course are: a) help students visualise and understand actual mechanical configurations with their constraints and practical limitations and, b) provide guidelines to formulate problems and relate theory and practice.

The specific objectives are: a) the ability to analyse the dynamics of solids which can be assimilated to particles representative of actual situations and problems; b) the understanding of some energy-based and conservation concepts and c), the ability to predict and control vibrations in mechanical systems.

 

Syllabus:

1 – Kinematics of particles: 

  • Velocity and acceleration, 
  • Plane motion 
  • Coordinate systems: normal-tangential, Cartesian, Polar 
  • Space curvilinear motion
  • Constrained motions of particles

2 – Kinetics of particles:

  • Force, mass and acceleration
  • Work and energy
  • Impulse and momentum

3 – Plane kinetics of rigid bodies:

  • Translation
  • Fixed-axis rotation

4 – Vibration and time-response:

  • Free vibration of particles
  • Forced vibration of particles
  • Introduction to rigid-body vibration
