Dynamics 2





Offered by

Mechanical Engineering




ME-DYN1 or equivalent

Main purpose

The course should teach the students how to use the laws of rigid body kinematics and kinetics, as well as a basic introduction to mechanical vibrations.


The students will get knowledge about:

* the kinematics of rigid body motion
* relative motion with both translation and rotation
* moment of inertia
* equations of motion for general planar motion
* energy in general planar motion
* undamped and viscous damped free vibration with a single degree of freedom.


After completing the course, the student will be able to:

* Use kinematic relations in the description of rigid body motion.
* Transform kinematic quantities between coordinate systems in relative motion.
* Set up and solve the equations of motion rigid bodies in general planar motion.
* Use energy methods to solve problems in rigid body dynamics
* Describe undamped and viscous damped free vibrations with a single degree of freedom.


After completing the course, the student can:

* Identify which parts of the acquired knowledge and skills that relevant to a given, simple real-world mechanical problem.
* Model simple real-world problems using the acquired knowledge and skills.
* Expand her/his knowledge on rigid body dynamics in more advanced courses.


Teaching methods and study activities

The expected total workload for the student is around 138 hours. The teaching will be lecturing and problem solving in class. Students will prepare for class by reading sections of textbook and solving problems posed by the lecturer.

Student Activity Model:
According to the Study Activity Model, the workload is divided as follows:

Category 1, Initiated by the lecturer with the participation of lecturer and students: 36 hours – 26%
Category 2: Initiated by lecturer with participation of students: 61 hours – 44 %
Category 3: Initiated by students with participation of students: 38 hours – 28 %
Category 4: Initiated by students with the participation of lecturer and students: 3 hours – 2%

Requirements for attending examination
A week before the exam, the student must upload solutions for the 10-15 problems selected as exam questions. These problems are announced no later than the last day of teaching.

Type of examination
Individual oral exam based upon a problem found by draw. The exam is a discussion with the students uploaded solution to the problem as starting point. Exam duration is approximately 20 minutes and there is no preparation.
External censor

Allowed tools

Same as ordinary and with identical problems
