# Dynamics 2

ME-DYN2

3.0

## Offered by

Mechanical Engineering

## ECTS

5

### Prerequisites

Introductory particle dynamics

### Main purpose

This course will teach the student how to apply kinematics and kinetics for the description of rigid body dynamics. It will also give an introduction to the description of mechanical vibrations

### Knowledge

After completing the course, the student can:

• account for the kinematics of rigid bodies
• reproduce the formulas for relative motion
• explain the definition of the mass moment of inertia
• reproduce Newtons Laws as appropriate for the kinetics of rigid bodies
• account for the mechanical energy of rigid bodies
• describe different kinds of vibrations for a system with one degree of freedom

### Skills

After completing the course, the student can:

• apply kinematic relations to in the description of rigid body motion
• transform kinematic quantities between coordinate systems in relative motion
• calculate mass moments of inertia
• set up and solve equations of motion for systems of rigid bodies in general planar motion
• apply energy methods in problems involving rigid bodies
• set up and solve equations of motion for free as well as viscously damped mechanical vibrations with one degree of freedom
• apply CAS software to calculations within dynamics

### Competences

After having completed the course, the student can:

• Identify which knowledge and which skills that are relevant for a given, simple mechanical problem
• Model simple, but realistic mechanical systems using the skills acquired
• Attend advanced courses in dynamics

### Teaching methods and study activities

The course duration is approximately 12 weeks with 4 lessons per week. The expected work load for the student is approximately 138 hours.
The teaching consists of lectures and problem solving in class. The student must prepare for classes by reading and solving problems.

### Examination

Prerequisites for exam:
On week before the exam, the student must hand in solutions of the 8-12 problems which have been chosen as exam questions. The students are informed about the choice of exam problems on the last day of teaching at the latest.

Exam type:
Individual oral exam based on a randomly chosen problem. The exam is a discussion based on the students solution. Duration is approximately 20 minutes.
There is no preparation time.
External co-examiner.

Tools allowed:
None

Re-exam:
As the ordinary exam with the same exercises. Solutions must be handed in again.
