Mechanics, as a branch of physics, is a fundamental discipline in engineering sciences. It deals with the description and prediction of the motion of bodies and the associated forces. In the modules Engineering Mechanics 1 and 2, time-independent forces and deformations in stationary, elastic bodies were considered. As such, these courses focused on solving static and elastostatic problems. Engineering Mechanics 3 now deals with bodies and systems that move in time, i.e. dynamic ones.

The basics of kinematics are introduced in the introduction. Kinematics deals exclusively with the description of a (rigid) body’s motion and how the necessary quantities to describe the motion can be measured and derived from one another.

The second chapter, kinetics, analyzes how the action of forces and moments can change the state of motion of a body or system by linking the causes (forces and moments) to the kinematic variables.

In the third chapter, the linear theory of vibrations is introduced. Vibrations are a subfield of kinetics, where bodies or systems have a regularity in their motion. However, we will limit ourselves to linear vibration problems in this lecture.

Course Objectives

A successful attendance to the module enables the students to...

  • ... clearly describe the motion of mechanical systems with the help of kinematic quantities.
  • ... apply mechanical principles, including energy methods, to describe a possible change in the state of motion of a dynamic mechanical system.
  • ... describe and analyze problems in the field of linear vibration theory.
